He is come to Aiath. The siege of the holy city being now at hand, Isaiah sets before their eyes the whole of Sennacherib's march, that the hearts of the godly, by long and careful study of it, may remain steadfast. This delineation was powerfully calculated to allay their fears, when godly men saw that the Assyrians did not move a step but by the appointment of God; for by the mouth of the Prophet he had given a lively description of the whole of that march. [1] It is unnecessary to spend much time in explaining the relative position of the places here named, for it is enough if we understand that Sennacherib marched through those places of which the Jews had been informed. At Michmash he will lay up his baggage. The words which we render, He will lay up his baggage or armor, are translated by some, He hath made a muster; for phqd (pakad) signifies also to number. I do not dislike this interpretation, but prefer the former; for I understand the Prophet to mean that the Assyrian will lay up his armor, that is, the provisions, and the rest of the implements of war, in Michmash. It is the custom of warriors not to lead forward an army without providing the means of support, which they lay up in a safe and convenient place, that the army may be supplied out of it with all that is needful. Under the word baggage or arms, he includes not only darts and swords, but all the supplies and provisions of war. The meaning of the word kly (cheli) is extensive, and includes every kind of implements, and thus resembles the word (vasa) which denotes vessels in the Latin language.

Footnotes

1 - "Here is a lively description of the march of Sennacherib's army, not that related below in chapter 36:1-22, but in his first invasion of Judea, when he passed Jerusalem to the northward on his way to Egypt; for so the places here mentioned indicate, stretching in order from the north to the west and south of that capital." -- Rosenmuller.

He is come to Aiath - These verses Isaiah 10:28-32 contain a description of the march of the army of Sennacherib as he approached Jerusalem to invest it. The description is expressed with great beauty. It is rapid and hurried, and is such as one would give who was alarmed by the sudden and near approach of an enemy - as if while the narrator was stating that the invader had arrived at one place, he had already come to another; or, as if while one messenger should say, that he had come to one place, another should answer that he was still nearer, and a third, that he was nearer still, so as to produce universal consternation. The prophet speaks of this as if he "saw" it (compare the note at Isaiah. 1): as if, with the glance of the eye, he sees Sennacherib advancing rapidly to Jerusalem. The general course of this march is from the northeast to the southwest toward Jerusalem, and it is possible still to follow the route by the names of the places here mentioned, and which remain at present.
All the places are in the vicinity of Jerusalem, and this shows how much his rapid approach was suited to excite alarm. The name עית ‛ayâth does not occur elsewhere; but עי ‛ay is often mentioned, and עיא ‛ayâ' is found in Nehemiah 11:31. Doubtless, the same city is meant. It was situated near Bethel eastward; Joshua 7:2. It was at this place that Joshua was repulsed on account of the sin of Achaz, though the city was afterward taken by Joshua, the king seized and hanged, and the city destroyed. It was afterward rebuilt, and is often mentioned; Ezra 2:28; Nehemiah 7:32. It is called by the Septuagint, Ἀγγαι Angai; and by Josephus, "Aina." In the time of Eusebius and Jerome, its site and scanty ruins were still pointed out, not far distant from Bethel toward the east. The name, however, has at present wholly perished, and no trace of the place now remains. It is probable that it was near the modern Deir Diwan, about three miles to the east of Bethel: "see" Robinson's "Bib. Researches," ii. pp. 119, 312, 313.
He is passed to Migron - That is, he does not remain at Aiath, but is advancing rapidly toward Jerusalem. This place is mentioned in 1-Samuel 14:2, from which it appears that it was near Gibeah, and was in the boundaries of the tribe of Benjamin, to the southwest of Ai and Bethel. No trace of this place now remains.
At Michmash - This was a town within the tribe of Ephraim, on the confines of Benjamin; Ezra 2:27; Nehemiah 7:31. This place is now called Mukhmas, and is situated on a slope or low ridge of land between two small wadys, or water-courses. It is now desolate, but bears the marks of having been a much larger and stronger place than the other towns in the neigchourhood. There are many foundations of hewn stones; and some columns are lying among them. It is about nine miles to the northeast of Jerusalem, and in the immediate neighborhood of Gibeah and Ramah. - Robinson's "Bib. Researches," ii. p. 117. In the time of Eusebius it was a large village. - "Onomast." Art. "Machmas."
He hath laid up his carriages - Hebrew, 'He hath deposited his weapons.' The word rendered "hath laid up" - יפקיד yapeqı̂yd - may possibly mean, "he reviewed," or he took an account of; that is, he made that the place of "review" preparatory to his attack on Jerusalem. Jerome says, that the passage means, that he had such confidence of taking Jerusalem, that he deposited his armor at Michmash, as being unnecessary in the siege of Jerusalem. I think, however, that the passage means simply, that he had made Michmash one of his "stations" to which he had come, and that the expression 'he hath deposited his armor there,' denotes merely that he had come there as one of his stations, and had pitched his camp in that place on the way to Jerusalem. The English word "carriage," sometimes meant formerly, "that which is carried," baggage, vessels, furniture, etc. - "Webster." In this sense it is used in this place, and also in 1-Samuel 17:22; Acts 21:15.

He is come to Aiath - A description of the march of Sennacherib's army approaching Jerusalem in order to invest it, and of the terror and confusion spreading and increasing through the several places as he advanced; expressed with great brevity, but finely diversified. The places here mentioned are all in the neighborhood of Jerusalem; from Ai northward, to Nob westward of it; from which last place he might probably have a prospect of Mount Sion. Anathoth was within three Roman miles of Jerusalem, according to Eusebius, Jerome and Josephus. Onomast. Loc. Hebr. et Antiq. Jude. 10:7, 3. Nob was probably still nearer. And it should seem from this passage of Isaiah that Sennacherib's army was destroyed near the latter of these places. In coming out of Egypt he might perhaps join the rest of his army at Ashdod, after the taking of that place, which happened about that time, (see Isaiah 20:1-6.); and march from thence near the coast by Lachish and Libnah, which lay in his way from south to north, and both which he invested till he came to the north-west of Jerusalem, crossing over to the north of it, perhaps by Joppa and Lydda; or still more north through the plain of Esdraelon.

He is come to (y) Aiath, he is passed to Migron; at Michmash he hath attended to his carriages:
(y) He describes by what way the Assyrians would come against Jerusalem, to confirm the faithful, when it would come to pass, that as their plague was come, so should they be delivered.

He is come to Aiath,.... In this and the following verses is prophetically described the expedition of Sennacherib to Jerusalem, when he either went from Assyria, or returned from Egypt thither; and the several places are mentioned, through or by which he passed, or near to which he came, the tidings of which greatly distressed the inhabitants of them; and the first that is named is Ajath, thought to be the same with Ai, which was beside Bethaven, and on the east side of Bethel, Joshua 7:2 and though it was burnt, and made desolate by Joshua, Joshua 8:28 yet it was afterwards rebuilt, for it was in being in Nehemiah's time; or at least there was a place of this name, which was upon or near the spot where this stood, since it is mentioned with Geba, Michmash, and Bethel, Nehemiah 11:31 according to the ancient Jewish writers (w), it lay three miles from Jericho. Jerom (x) calls it Agai, and says that in his time there was scarce any remains of it, only the place was shown.
He is passed to Migron; this place, as the former, was in the tribe of Benjamin; mention is made of it, as in the uttermost part of Gibeah, 1-Samuel 14:2. Sennacherib seems not to have stayed either in this, or the former place:
at Michmash he hath laid up his carriages; here was a passage, called the passage of Michmash, where was the garrison of the Philistines; and on each side of it were two rocks, one called Bozez, and the other Seneh; one of which fronted Michmash to the north, and the other Gibeah to the south, 1-Samuel 13:23 by Josephus (y) it is called Mechmas, a city; and so it is in the Apocrypha:
"Thus the sword ceased from Israel: but Jonathan dwelt at Machmas, and began to govern the people; and he destroyed the ungodly men out of Israel.'' (1 Maccabees 9:73)
In Jerom's time it was a very large village, who says it was nine miles from Jerusalem (z): mention is made of it in the Misna (a), as famous for the best fine flour; and this the king of Assyria made his magazine, and in it laid up his provisions and warlike stores, from whence he might be supplied upon occasion. The words may be rendered, "he hath laid up his arms"; and Kimchi thinks he left the greatest part of his arms here, and went in haste to Jerusalem, imagining he should have no occasion for them, but should easily take it. The Targum is,
"at Micmas he shall appoint the princes of his army;''
the generals of it: perhaps the sense is, that here he made a muster of his army, examined the arms of his soldiers, appointed the proper officers, and gave them their instructions.

Aesthetically considered, the description is one of the most magnificent that human poetry has ever produced. "He comes upon Ayyath, passes through Migron; in Michmash he leaves his baggage. They go through the pass: let Geba be our quarters for the night! Ramah trembles; Gibeah of Saul flees. Scream aloud, O daughter of Gallim! Only listen, O Laysha! Poor Anathoth! Madmenah hurries away; the inhabitants of Gebim rescue. He still halts in Nob today; swings his hand over the mountain of the daughter of Zion, the hill of Jerusalem. Behold, the Lord, Jehovah of hosts, lops down the branches with terrific force; and those of towering growth are hewn down, and the lofty are humbled. And He fells the thickets of the forest with iron; and Lebanon, it falls by a Majestic One." When the Assyrian came upon Ayyath (= Ayyah, 1-Chronicles 7:28 (?), Nehemiah 11:31, generally hâ-‛ai, or 'Ai), about thirty miles to the north-east of Jerusalem, he trod for the first time upon Benjaminitish territory, which was under the sway of Judaea. The name of this 'Ai, which signifies "stone-heap," tallies, as Knobel observes, with the name of the Tell el-hagar, which is situated about three-quarters of an hour to the south-east of Beitn, i.e., Bethel. But there are tombs, reservoirs, and ruins to be seen about an hour to the south-east of Beitin; and these Robinson associates with Ai. From Ai, however, the army will not proceed towards Jerusalem by the ordinary route, viz., the great north road (or "Nablus road"); but, in order to surprise Jerusalem, it takes a different route, in which it will have to cross three deep and difficult valleys. From Ai they pass to Migron, the name of which has apparently been preserved in the ruins of Burg Magrun, situated about eight minutes' walk from Beitn.
(Note: I also find the name written Magrum (read Magrun), which is probably taken from a more correct hearsay than the Machrn of Robinson (ii. 127).)
Michmash is still to be found in the form of a deserted village with ruins, under the name of Muchms, on the eastern side of the valley of Migron. Here they deposit their baggage (hiphkid, Jeremiah 36:20), so far as they are able to dispense with it - either to leave it lying there, or to have it conveyed after them by an easier route. For they proceed thence through the pass of Michmash, a deep and precipitous ravine about forty-eight minutes in breadth, the present Wady Suweinit. "The pass" (ma‛bârâh) is the defile of Michmash, with two prominent rocky cliffs, where Jonathan had his adventure with the garrison of the Philistines. One of these cliffs was called Seneh (1-Samuel 14:4), a name which suggests es-Suweinit. Through this defile they pass, encouraging one another, as they proceed along the difficult march, by the prospect of passing the night in Geba, which is close at hand. It is still disputed whether this Geba is the same place as the following Gibeah of Saul or not. There is at the present time a village called Geba' below Muchms, situated upon an eminence. The almost universal opinion now is, that this is not Gibeah of Saul, but that the latter is to be seen in the prominent Tell (Tuleil) el-Fl, which is situated farther south. This is possibly correct.
(Note: This is supported by Robinson in his Later Biblical Researches in Palestine (1857), by Valentiner (pastor at Jerusalem), and by Keil in the Commentary on Joshua, Judges, etc. (Joshua 18:21-28), where all the more recent writings on this topographical question are given.)
For there can be no doubt that this mountain, the name of which signifies "Bean-hill," would be a very strong position, and one very suitable for Gibeah of Saul; and the supposition that there were two places in Benjamin named Geba, Gibeah, or Gibeath, is favoured at any rate by Joshua 18:21-28, where Geba and Gibeath are distinguished from one another. And this mountain, which is situated to the south of er-Rm - that is to say, between the ancient Ramah and Anathoth - tallies very well with the route of the Assyrian as here described; whilst it is very improbable that Isaiah has designated the very same place first of all Geba, and then (for what reason no one can tell) Gibeah of Saul. We therefore adopt the view, that the Assyrian army took up its quarters for the night at Geba, which still bears this name, spreading terror in all directions, both east and west, and still more towards the south. Starting in the morning from the deep valley between Michmash and Geba, they pass on one side of Rama (the present er-Rm), situated half an hour to the west of Geba, which trembles as it sees them go by; and the inhabitants of Gibeath of Saul, upon the "Bean-hill," a height that commands the whole of the surrounding country, take to flight when they pass by. Every halting-place on their route brings them nearer to Jerusalem. The prophet goes in spirit through it all. It is so objectively real to him, that it produces the utmost anxiety and pain. The cities and villages of the district are lost.
He appeals to the daughter, i.e., the population, of Gallim, to raise a far-sounding yell of lamentation with their voice (Ges. 138, 1, Anm. 3), and calls out in deep sympathy to Laysha, which was close by (on the two places, both of which have vanished now, see 1-Samuel 25:44 and Judges 18:29), "only listen," the enemy is coming nearer and nearer; and then for Anathoth (‛Anâtâ, still to be seen about an hour and a quarter to the north of Jerusalem) he utters this lamentation (taking the name as an omen of its fate): O poor Anathoth! There is no necessity for any alteration of the text; ‛anniyâh is an appeal, or rather an exclamation, as in Isaiah 54:11; and ‛anâthoth follows, according to the same verbal order as in Isaiah 23:12, unless indeed we take it at once as an adjective written before the noun - an arrangement of the words which may possibly have been admissible in such interjectional sentences. The catastrophe so much to be dreaded by Jerusalem draws nearer and nearer. Madmenah (dung-hill, see Comm. on Job, at Job 9:11-15) flees in anxious haste: the inhabitants of Gebim (water-pits) carry off their possessions (הּעיז, from עוּז, to flee, related to chush, hence to carry off in flight, to bring in haste to a place of security, Exodus 9:19, cf., Jeremiah 4:6; Jeremiah 6:1; synonymous with hēnı̄s, Exodus 9:20; Judges 6:11; different from ‛âzaz, to be firm, strong, defiant, from which mâ‛oz, a fortress, is derived - in distinction from the Arabic ma‛âdh, a place of refuge: comp. Isaiah 30:2, to flee to Pharaoh's shelter). There are no traces left of either place. The passage is generally understood as implying that the army rested another day in Nob. But this would be altogether at variance with the design - to take Jerusalem by surprise by the suddenness of the destructive blow. We therefore render it, "Even to-day he will halt in Nob" (in eo est ut subsistat, Ges. 132, Anm. 1) - namely, to gather up fresh strength there in front of the city which was doomed to destruction, and to arrange the plan of attack. The supposition that Nob was the village of el-'Isawiye, which is still inhabited, and lies to the south-west of Ant, fifty-five minutes to the north of Jerusalem, is at variance with the situation, as correctly described by Jerome, when he says: "Stans in oppidulo Nob et procul urbem conspiciens Jerusalem." A far more appropriate situation is to be found in the hill which rises to the north of Jerusalem, and which is called Sadr, from its breast-like projection or roundness - a name which is related in meaning to nob, nâb, to rise. From this eminence the way leads down into the valley of Kidron; and as you descend, the city spreads out before you at a very little distance off. It may have been here, in the prophet's view, that the Assyrians halted.
(Note: This is the opinion of Valentiner, who also regards the march of the Assyrians as an "execution-march" in two columns, one of which took the road through the difficult ground to the east, whilst the other inflicted punishment upon the places that stood near the road. The text does not require this, however, but describes a march, which spread alarm both right and left as it went along.)
It was not long, however (as the yenōphēph which follows ἀσυνδέτως implies), before his hand was drawn out to strike (Isaiah 11:15; Isaiah 19:16), and swing over the mountain of the daughter of Zion (Isaiah 16:1), over the city of the holy hill. But what would Jehovah do, who was the only One who could save His threatened dwelling-place in the face of such an army? As far as Isaiah 10:32, the prophet's address moved on at a hurried, stormy pace; it then halted, and seemed, as it were, panting with anxiety; it now breaks forth in a dactylic movement, like a long rolling thunder. The hostile army stands in front of Jerusalem, like a broad dense forest. But it is soon manifest that Jerusalem has a God who cannot be defied with impunity, and who will not leave His city in the lurch at the decisive moment, like the gods of Carchemish and Calno. Jehovah is the Lord, the God of both spiritual and starry hosts. He smites down the branches of this forest of an army: sē‛ēph is a so-called piel privativum, to lop (lit. to take the branches in hand; cf., sikkēl, Isaiah 5:2); and pu'rah = pe'urah (in Ezekiel pō'rah) is used like the Latin frons, to include both branches and foliage - in other words, the leafy branches as the ornament of the tree, or the branches as adorned with leaves. The instrument He employs is ma‛arâtzâh, his terrifying and crushing power (compare the verb in Isaiah 2:19, Isaiah 2:21). And even the lofty trunks of the forest thus cleared of branches and leaves do not remain; they lie hewn down, and the lofty ones must fall. It is just the same with the trunks, i.e., the leaders, as with the branches and the foliage, i.e., with the great crowded masses. The whole of the forest thicket (as in Isaiah 9:17) he hews down (nikkaph, third pers. piel, though it may also be niphal); and Lebanon, i.e., the army of Asshur which is now standing opposite to Mount Zion, like Lebanon with its forest of cedars, falls down through a Majestic One ('addı̄r), i.e., through Jehovah (Isaiah 33:21, cf., Psalm 76:5; Psalm 93:4). In the account of the fulfilment (Isaiah 37:36) it is the angel of the Lord (mal'ach Jehovah), who is represented as destroying the hundred and eighty-five thousand in the Assyrian camp in a single night. The angel of Jehovah is not a messenger of God sent from afar, but the chosen organ of the ever-present divine power.

He - Here the prophet returns to the Assyrian invasion; which he describes, after the manner of the prophets, as a thing present, and sets down the several stages by which he marched towards Jerusalem. He, Sennacherib, king of Assyria, is come, in his way to Jerusalem. Laid up - Leaving such things there as were less necessary, that so he might march with more expedition.
