Inflaming yourselves. Others render it, "Taking delight" or "consolation;" but the Prophet makes use of a metaphor which is often found in Scripture, and which is exceedingly adapted to the present subject; for the Lord compares the ardor by which idolaters are hurried along to the love of a harlot, by which poor wretched men are inflamed so as to be transported with blind eagerness. (Jeremiah 3:1; Hosea 2:2; 4:5) Idolaters have no moderation, and do not permit themselves to be reclaimed from their madness by any arguments. In the sight of God idolatry is a very base kind of fornication. Under the oaks, or, with the gods. Some translate 'lym (elim) "gods," and others "oaks." [1] I leave every one at liberty to adopt either reading; for the meaning will always be the same, and commentators are agreed that the Prophet condemns idolatry. I do not dispute, therefore, about the reading; though it is probable that the same thing is twice repeated, in accordance with the practice of Hebrew writers, in a particular and in a general form, and yet that the Prophet, by means of an ambiguous word, alludes to "the gods." Sacrificing children. Here he bears still harder on the Jews, and shows that they are not the true seed of Abraham; seeing that they pollute themselves with superstitions of every kind. In consequence of the delight which the Jews took in such practices, he exposes their vileness. "You shelter yourselves, indeed, under the name of religion, but I declare that you commit fornication with idols." In this manner it was proper to expose and freely to point out that wickedness which base and malicious men endeavor to cloak under various pretenses; and thus the Prophet boldly discharges his duty by summoning men to the judgmentseat of God, and holding them to be guilty, though they wish to take every method of excusing themselves. He shows that they are treacherous, and have departed from the law of God by abominable idolatry, and mentions one kind of shocking and even accursed and monstrous worship; namely, the "sacrificing of children," from which it is very evident how powerful is the spirit of error, when men have once turned aside from God. Satan seizes their minds (2-Thessalonians 2:9) in such a manner that he drives them altogether to madness and rage. They who do not hesitate to slay their children, as if on the ground of its being a righteous sacrifice, must be in a state of furious madness. And yet those cruel murderers of their children did not want some pretense; for they cloaked their crime under the example of Abraham, who did. not spare (Genesis 22:16) his onlybegotten son; and the ancient Hebrew writers pronounce it to have been (kakozelia) a wicked imitation "If we are Abraham's descendants, we ought not to spare our children." But Abraham did this (Genesis 22:2) by the command of God; while they did it of their own accord, and without God's command. It was an extraordinary example, by which the Lord intended to try and attest Abraham's faith. Besides, Isaac was not sacrificed; for the Lord was satisfied with Abraham's cheerful and ready will. (Genesis 22:12) They slew their children. It was, therefore, a perverse and damnable imitation, for they differed widely from their father This should be carefully observed; for a large portion of superstitions has proceeded from this source of (kakozelia) wicked imitation. Men have rashly and without discrimination seized on everything that was done by the fathers.

Footnotes

1 - See Commentary on Isaiah, [8]Vol. 1, p. 84, n. 1.

Inflaming yourselves - Burning, that is, with lust. The whole language here is derived from adulterous intercourse. The sense is, that they were greatly addicted to idolatry, and that they used every means to increase and extend the practice of it. The Vulgate, however, renders this, 'Who console yourselves.' The Septuagint renders it, 'Invoking (παρακαλοῦντες parakalountes) idols.' But the proper meaning of the Hebrew word חמם châmam is, "to become warm; to be inflamed, or to burn as with lust."
With idols - Margin, 'Among the oaks.' Hebrew, באלים bā'ēlı̂ym. Vulgate, In diis - 'With the gods.' Septuagint, Εἴδωλα Eidōla - 'Idols.' So the Chaldee and Syriac. The Hebrew may denote 'with gods,' that is, with idol-gods; or it may denote, as in the margin, 'among the oaks,' or the terebinth groves, from איל 'ēyl, plural אילים 'ēylı̂ym, or אלים 'ēlym (the terebinth). See the word explained in the note at Isaiah 1:29. Kimchi and Jarchi here render it by 'the terebinth tree.' Lowth renders it, 'Burning with the lust of idols;' and probably this is the correct interpretation, for, if it had meant oaks or the terebinth tree, the phrase would have been "under" (תחת tachath) instead of "in" or "with" (ב b).
Under every green tree - (See the notes at Isaiah 1:29; compare Deuteronomy 22:2; 2-Kings 17:10; 2-Chronicles 28:4).
Slaying the children - That is, sacrificing them to the idol-gods. This was commonly done by burning them, as when they were offered to Moloch, though it is not improbable that they were sometimes sacrificed in other ways. It was a common custom among the worshippers of Moloch. Thus it is said of Ahaz 2-Chronicles 28:3, that he 'burnt incense in the valley of the son of Hinnom, and burnt his children in the fire.' The same thing is said of Manasseh, to whose time the prophet most probably refers. 'And he caused his children to pass through the fire in the valley of the son of Hinnom' (2-Chronicles 33:6; compare Jeremiah 7:31). The same thing was practiced in the countries of the Babylonian empire 2-Kings 17:31, and from Deuteronomy 12:31, it is evident that it was commonly practiced by pagan nations. The Phenicians, according to Eusebius (Praep. Evan. iv. 16), and the Carthagenians, according to Diodorus Siculus (xx. 14), practiced it.
In the valleys - The place where these abominations were practiced by the Jews was the valley of the son of Hinnom (see the references above); that is, the valley of Jehoshaphat, lying to the south and the southeast of Jerusalem. A large hollow, brass statue was erected, and the fire was enkindled within it, and the child was placed in his heated arms, and thus put to death. The cries of the child were drowned by the music of the תף tôph, or kettle-drums (see the notes at Isaiah 5:12, where this instrument is fully described), and hence, the name of the valley was Tophet.
Under the clefts of the rocks - Dark and shady groves, and deep and sombre caverns were the places where the abominable rites of the pagan superstitions were practiced (compare the notes at Isaiah 11:1).

Inflaming yourselves with idols under every green tree, slaying the (d) children in the valleys under the clefts of the rocks?
(d) Read (Leviticus 18:21; 2-Kings 23:10).

Inflaming yourselves with idols under every green tree,.... Or, "inflamed with or among oaks" (h); with images made of oaken wood, such as the Papists worship, Revelation 9:20 expressing a burning zeal for their idols, and being as hot upon them, as impure persons burn in lust one towards another: or "with mighty ones" (i); the kings and potentates of the earth, with whom the whore of Rome commits her fornication, even in every flourishing kingdom and state in Europe, compared to a green tree; alluding to the custom of the Heathens, who used to set up their idols under green trees and groves, and there worship them, which were pleasing to the flesh; and I wish, says Musculus on the text, there were no instances of this kind in the Papacy.
Slaying the children in the valleys, under the clifts of the rocks? this may refer to the cruelty of these idolatrous worshippers; for, as they burn with zeal to their idols, so with rage against those that oppose their idolatrous practices, not sparing men, women, and children; and such butcheries have been committed in many places, and especially in the "valleys" of Piedmont; nor could the cragged rocks secure them from their falling a sacrifice unto them. Or it may intend the ruining and destroying the souls of such, who, before they fell into their hands, were innocent as children, by their superstitious worship and idolatry, committed in low and dark places, under cragged rocks, and in caves and dens; such as the above mentioned commentator speaks of, a very dark one, under a prominent rock, in which the ignorant and unhappy people, some time ago, worshipped and invoked a certain blessed saint, he knew not who, which could scarce be looked into without horror; and such was the cave in which they worshipped the angel Michael.
(h) "inflammati inter quercus", Gataker; "incalescentes, vel incalescitis inter quercus, vel ulmos", Vatablus. (i) "In potentibus", Cocceius.

Enflaming yourselves--burning with lust towards idols [GESENIUS]; or else (compare Margin), in the terebinth groves, which the Hebrew and the parallelism favor (see on Isaiah 1:29) [MAURER].
under . . . tree-- (2-Kings 17:10). The tree, as in the Assyrian sculptures, was probably made an idolatrous symbol of the heavenly hosts.
slaying . . . children--as a sacrifice to Molech, &c. (2-Kings 17:31; 2-Chronicles 28:3; 2-Chronicles 33:6).
in . . . valleys--the valley of the son of Hinnom. Fire was put within a hollow brazen statue, and the child was put in his heated arms; kettle drums (Hebrew, toph) were beaten to drown the child's cries; whence the valley was called Tophet (2-Chronicles 33:6; Jeremiah 7:3).
under . . . clifts--the gloom of caverns suiting their dark superstitions.

The participles which follow in the next v. are in apposition to אתּ, and confirm the predicates already applied to them. They soon give place, however, to independent sentences. "Ye that inflame yourselves by the terebinths, under every green tree, ye slayers of children in the valleys under the clefts of the rocks. By the smooth ones of the brook was thy portion; they, they were thy lot: thou also pouredst out libations to them, thou laidst meat-offerings upon them. Shall I be contented with this?" The people of the captivity are addressed, and the idolatry handed down to them from their ancestors depicted. The prophet looks back from the standpoint of the captivity, and takes his colours from the time in which he himself lived, possibly from the commencement of Manasseh's reign, when the heathenism that had for a long time been suppressed burst forth again in all its force, and the measure of iniquity became full. The part. niphal הנּחמים is formed like נחן in Jeremiah 22:23, if the latter signifies miserandum esse. The primary form is נחם, which is doubled like נגּר from גּרר in Job 20:28, and from which נחם is formed by the resolution of the latent reduplication. Stier derives it from; but even if formed from this, נחם would still have to be explained from נחם, after the form נצּת. 'Elı̄m signifies either gods or terebinths. But although it might certainly mean idols, according to Exodus 15:11; Daniel 11:36 (lxx, Targ., and Jerome), it is never used directly in this sense, and Isaiah always uses the word as the name of a tree (Isaiah 1:29; Isaiah 61:3). The terebinths are introduced here, exactly as in Isaiah 1:29, as an object of idolatrous lust: "who inflame themselves with the terebinths;" ב denotes the object with which the lust is excited and inf Lamed. The terebinth ('ēlâh) held the chief place in tree-worship (hence אלנם, lit., oak-trees, together with אלם, is the name of one of the Phoenician gods),
(Note: See Levy, Phnizische Studien, i. 19.)
possibly as being the tree sacred to Astarte; just as the Samura Acacia among the heathen Arabs was the tree sacred to the goddess 'Uzza.
(Note: Krehl, Religioin der vorisl. Araber, p. 74ff.)
The following expression, "under every green tree," is simply a permutative of the words "with the terebinths" in the sense of "with the terebinths, yea, under every green tree" (a standing expression from Deuteronomy 12:2 downwards) - one tree being regarded as the abode and favourite of this deity, and another of that, and all alluring you to your carnal worship.
From the tree-worship with its orgies, which was so widely spread in antiquity generally, the prophet passes to the leading Canaanitish abomination, viz., human sacrifices, which had been adopted by the Israelites (along with שׁחטי we find the false reading שׂחטי, which is interpreted as signifying self-abuse). Judging from the locality named, "under the clefts of the rocks," the reference is not to the slaying of children sacrificed to Moloch in the valley of Hinnom, but to those offered to Baal upon his bâmōth or high places (Jeremiah 19:5; Ezekiel 16:20-21; Hosea 13:2; Psalm 106:37-38). As we learn from the chronique scandaleuse many things connected with the religious history of Israel, which cannot be found in its historical books, there is nothing to surprise us in the stone-worship condemned in Isaiah 57:6. The dagesh of חלּקי is in any case dagesh dirimens. The singular is wither חלק after the form חכמי (cf., עצבי, Isaiah 58:3), or חלק after the form ילדי. But חלק, smoothness, never occurs; and the explanation, "in the smoothnesses, i.e., the smooth places of the valley, is thy portion," has this also against it, that it does not do justice to the connection בּ חלק, in which the preposition is not used in a local sense, and that it leaves the emphatic הם הם quite unexplained. The latter does not point to places, but to objects of worship for which they had exchanged Jehovah, of whom the true Israelite could say ה חלקי, Psalm 119:57, etc., or בה לי חלק, Joshua 22:25, and גּורלי תּומיך אתּה (Thou art He that maintaineth my lot), Psalm 16:5. The prophet had such expressions as these in his mind, and possibly also the primary meaning of גורל = κλῆρος, which may be gathered from the rare Arabic word 'garal, gravel, stones worn smooth by rolling, when he said, "In the smooth ones of the valley is thy portion; they, they are thy lot." In the Arabic also, achlaq (equilvaent to châlâq, smooth, which forms here a play upon the word with חלק, châlâq) is a favourite word for stones and rocks. חלּקי־נחל, however, according to 1-Samuel 17:40 (where the intensive form חלּוּק, like שׁכּוּל, is used), are stones which the stream in the valley has washed smooth with time, and rounded into a pleasing shape. The mode of the worship, the pouring out of libations,
(Note: Compare the remarks made in the Comm. on the Pentateuch, at Genesis 29:20, on the heathen worship of anointed stones, and the Baetulian worship.)
and the laying of meat-offerings upon them, confirm this view. In Carthage such stones were called abbadires (= אדיר, אבן); and among the ancient Arabs, the asnâm or idols consisted for the most part of rude blocks of stone of this description. Herodotus (3:8) speaks of seven stones which the Arabs anointed, calling upon the god Orotal. Suidas (s.v. Θεῦς ἄρης) states that the idol of Ares in Petra was a black square stone; and the black stone of the Ka'aba was, according to a very inconvenient tradition for the Mohammedans, an idol of Saturn (zuhal).
(Note: See Krehl, p. 72. In the East Indies also we find stone-worship not only among the Vindya tribes (Lassen, A.K. i. 376), but also among the Vaishnavas, who worship Vishnu in the form of a stone, viz., the sâlagrâm, a kind of stone from the river Gandak (see Wilson's Sanscrit Lexicon s.h.v. and Vishnu-Purn, p. 163). The fact of the great antiquity of stone and tree worship has been used in the most ridiculous manner by Dozy in his work on the Israelites at Mecca (1864). He draws the following conclusion from Deuteronomy 32:18 : "Thus the Israelites sprang from a divine block of stone; and this is, in reality, the true old version of the origin of the nation." From Isaiah 51:1-2, he infers that Abraham and Sara were not historical persons at all, but that the former was a block of stone, and the latter a hollow; and that the two together were a block of stone in a hollow, to which divine worship was paid. "This fact," he says, "viz. that Abraham and Sarah in the second Isaiah are not historical persons, but a block of stone and a hollow, is one of great worth, as enabling us to determine the time at which the stories of Abraham in Genesis were written, and to form a correct idea of the spirit of those stories.")
Stone-worship of this kind had been practised by the Israelites before the captivity, and their heathenish practices had been transmitted to the exiles in Babylon. The meaning of the question, Shall I comfort myself concerning such things? - i.e., Shall I be contented with them (אנּחם niphal, not hithpael)? - is, that it was impossible that descendants who so resembled their fathers should remain unpunished.

Enflaming - Lusting after them, and mad upon them. Slaying - In way of sacrifice to their idols. Valleys - He seems to allude to the valley of Hinnom in which these cruelties were practised. Clifts - Which they chuse either for shade, or for those dark vaults, in rocks, which were convenient for idolatrous uses.
