The morning cometh. This means that the anxiety will not last merely for a single day, or for a short time, as if the watchman had replied, "What I tell you to-day, I will tell you again to-morrow; if you are afraid now, you will also be afraid to-morrow." It is a most wretched condition when men are tortured with anxiety, in such a manner that they hang in a state of doubt between death and life; and it is that dismal curse which the Lord threatens against wicked men by Moses, "Would that I lived till the evening; and in the evening, would that I saw the dawn!" (Deuteronomy 28:67.) The godly indeed are beset with many dangers, but they know that they and their life are committed to the hand of God, and even in the jaws of death they see life, or at least soothe their uneasy fears by hope and patience. But the wicked always tremble, and not only are tormented by alarm, but waste away in their sorrows. Return, come. These words may be explained in two ways; either that if they run continually, they will lose their pains, or in this way, "If any among you be more careful, let them go to Dumah, and there let them tremble more than in their native country, for nowhere will they be safe." But since God always takes care of his Church, nowhere shall we find a safer retreat, even though we shall compass sea and land.

The watchman said - Or rather "saith;" indicating that this is the answer which the prophet returned to the inquiry from Idumea.
The morning cometh - There are signs of approaching day. The 'morning' here is an emblem of prosperity; as the light of the morning succeeds to the darkness of the night. This refers to the deliverance from the captivity of Babylon, and is to be supposed as having been spoken near the time when that captivity was at an end - or nearly at break of day after the long night of their bondage. This declaration is to be understood as referring to a different people from those referred to in the expression which immediately follows - 'and also the night.' 'The morning cometh' - to the captive Jews; 'and also the night' - to some other people - to wit, the Idumeans. It "might" mean that the morning was to be succeeded by a time of darkness to the same people; but the connection seems to demand that we understand it of others.
And also the night - A time of calamity and affliction. This is emphatic. It refers to the Idumeans. 'The morning cometh to the captive Jews; it shall be closely succeeded by a night - a time of calamity - to the taunting Idumeans.' During the captivity of the Jews in Babylon, the Idumeans invaded and took possession of the southern part of Judea. The prophet here refers to the fact, perhaps, that on the return of the Jews to their native land, they would revenge this by expelling them, and by inflicting punishment on the land of Edom. For a full proof that calamities came upon the land of Idumea, see Keith "On the Prophecies." Art. "Idumea," and the notes at Isaiah. 34)
If ye will inquire, inquire ye - If you choose to ask anything further in regard to this, you can. The sense is probably this: 'You Idumeans have asked respecting the night in derision and reproach. An answer has been given somewhat agreeably to that inquiry. But if you seriously wish to know anything further respecting the destiny of your land, you can ask me (Isaiah) or any other prophet, and it will be known. But ask it in seriousness and earnestness, and with a suitable regard for the prophetic character and for God. And especially if you wish a more favorable answer to your inquiries, it is to be obtained only by forsaking sin and turning to God, and then you may come with the hope of a brighter prospect for the future.' The design of this is, therefore:
(1) to "reprove" them for the manner in which they had asked the question;
(2) to assure them that God was willing to direct humble and serious inquirers; and
(3) to show in what way a favorable answer could be obtained - to wit, by repentance. And this is as true of sinners now as it was then. "They" often evince the reproachful and taunting spirit which the Idumeans did. "They" hear only a similar response - that prosperity and happiness await the Christian, though now in darkness and affliction; and that calamity and destruction are before the guilty. They "might" have the same answer - an answer that God would bless them and save them, if they would inquire in a humble, serious, and docile manner.
Return - Turn from your sins; come back to God, and show respect for him and his declarations.
Come - "Then" come and you shall be accepted, and the watch man will also announce "morning" as about to dawn on you. This seems to be the sense of this very dark and difficult prophecy. It is brief, enigmatical, and obscure. Yet it is beautiful; and if the sense above given be correct, it contains most weighty and important truth - alike for the afflicted and persecuted friends, and the persecuting and taunting foes of God. With reference to the interpretation here proposed, which supposes, as will have been seen:
(1) a state of excited feeling on the part of the Jews toward the Idumeans, for the part which they took in the destruction of their city;
(2) the prospect of speedy deliverance to the Jews in Babylon; and
(3) a consequent desolation and vengeance on the Idumeans for the feelings which they had manifested in the destruction of Jerusalem, see the prophecy of Obadiah, Obadiah 1:8-21 :
Shall I not in that day, saith the Lord,
Even destroy the wise men out of Edom,
And understanding out of the mount of Esau?
And thy mighty men, O Teman, shall be dismayed,
To the end that every one of the mount of Esau
May be cut off by slaughter.
For thy violence against thy brother Jacob shame shall cover thee,
And thou shalt be cut off for ever.
In the day that thou stoodest on the other side;
In the day that the stranger carried away captive his forces;
And foreigners entered into his gates, and cast lots upon Jerusalem;
Even thou wast as one of them.
But thou shouldest not have looked on the day of thy brother
In the day that he became a stranger;
Neither shouldest thou have rejoiced over the children of Judah
In the day of their destruction;
Neither shouldest thou have spoken proudly in the day of distress.
For the day of the Lord is near upon all the heathen;
As thou hast done, it shall be done unto thee;
Thy reward shall return upon thine own head, etc.
In this prophecy these circumstances are all to be found;
(1) the hostility of the Edomites against Jerusalem, and the part which they took in the destruction of the city, in Isaiah 21:10-14;
(2) the fact of the deliverance of the Jews from captivity, in Isaiah 22:17;
(3) the consequent vengeance upon the Idumeans Isaiah 34:5-6.
This remarkable coincidence in an independent prophecy is a strong circumstance to prove that the interpretation above proposed is correct. In regard to the general reasons for the interpretation here proposed, and the lessons which the prophecy is suited to convey, I may be permitted to refer to my "Practical Sermons," pp. 325-341.

The watchman said, The (q) morning cometh, and also the night: if ye will enquire, enquire ye: return, come.
(q) He describes the unquietness of the people of Dumah, who were night and day in fear of their enemies, and ever ran to and fro to enquire news.

The watchman said, the morning cometh, and also the night,.... Not only a morning, but a night; and as sure as the morning comes, so shall the night; there wilt be a constant succession of morning and night; as a morning of prosperity, so a night of adversity: the morning of the Gospel dispensation was coming on, or of Christ's coming in the flesh, which was attended with joy and cheerfulness; like the morning, it dispersed the shadows of the law, introduced light, which gradually and irresistibly spread itself over the Gentile world; but then followed a night of darkness to the Jews, blindness happened to them, which still continues; and to the Arabians, Saracens, and Turks, when the bottomless pit was opened by Mahomet, which let out smoke and locusts in the eastern part of the world; and to the western part, when the Romish antichrist established himself as universal bishop: a morning came on again at the Reformation, and a night will follow, which is now begun; it is already a time of darkness, coldness, sleepiness, and of error and heresy, which will issue in an eventide, in a dark night: if it be asked what time it is with us, or how far we are gone toward the night? the answer is, we are in and toward the close of the Sardian church state; we are in the twilight, or in that part of time which is neither day nor night, Zac 14:6 the slaying of the witnesses is yet to come, which, with the general spread of Popery all over Christendom, will make it entire night; after which will come on the morning of the spiritual reign of Christ, when the light of the Gospel will be spread everywhere, and joy and gladness will attend the saints in all places; and it will be a time of great prosperity, both spiritual and temporal; which will be succeeded by another night of coldness, deadness, and carnal security, and will last till the second and personal coming of Christ; which will bring on the morning of a glorious resurrection to the saints, after which there will be no more night to them, though there will be an eternal one to the wicked. The Targum is,
"the prophet said, there is a reward for the righteous, and punishment for the wicked;''
and so the Jews elsewhere (d) interpret it of the morning of redemption to the righteous, and of the night of darkness to the wicked; or, as they sometimes express it (e), the morning is for the righteous, and the night for the wicked; the morning for Israel, and the night for the nations of the world. Dumah they sometimes (f) make to be the angel appointed over spirits, who they suppose gather together, and say to him, "watchman", &c.
if ye will inquire, inquire ye; seriously and in good earnest, diligently and constantly, with all humility and reverence, by prayer to God and by searching the Scriptures, and by application to the watchmen, the ministers of the word, who make it their business to study it, and have the mind of Christ:
return, come; return by repentance, and come to God, who receives backsliders, heals their backslidings, and loves them freely; or, "come again", to the watchman, and to the Lord, and renew your inquiries till you get satisfaction.

Reply of the prophet, The morning (prosperity) cometh, and (soon after follows) the night (adversity). Though you, Idumeans, may have a gleam of prosperity, it will soon be followed by adversity again. Otherwise, as BARNES, "Prosperity cometh (to the Jews) to be quickly followed by adversity (to you, Idumeans, who exult in the fall of Jerusalem, have seized on the southern part of their land in their absence during the captivity, and now deride them by your question)" (Isaiah 34:5-7). This view is favored by Obadiah 1:10-21.
if ye will inquire, inquire--If ye choose to consult me again, do so (similar phrases occur in Genesis 43:14; 2-Kings 7:4; Esther 4:16).
return, come--"Be converted to God (and then), come" [GESENIUS]; you will then receive a more favorable answer.
Probably in the wars between Assyria and Egypt; Idumea and Arabia lay somewhat on the intermediate line of march.

"Watchman says, Morning cometh, and also night. Will ye inquire, inquire! Turn, come!!" The answer is intentionally and pathetically expressed in an Aramaean form of Hebrew. אתא (written even with א at the end, cf., Deuteronomy 33:2) is the Aramaean word for בּוא; and בּעה בּעא) the Aramaean word for שׁאל, from the primary form of which (בּעי) the future tib‛âyūn is taken here (as in Isaiah 33:7), and the imperative be'ây (Ges. 75, Anm. 4). אתיוּ, which is here pointed in the Syriac style, אתיוּ, as in Isaiah 56:9, Isaiah 56:12, would be similarly traceable to אתי (cf., Ges. 75, Anm. 4, with 23, Anm. 2). But what is the meaning? Luther seems to me to have hit upon it: "When the morning comes, it will still be night." But v'gam (and also) is not equivalent to "and yet," as Schrring explains it, with a reference to Ewald, 354, a. With the simple connection in the clauses, the meaning cannot possibly be, that a morning is coming, and that it will nevertheless continue night, but that a morning is coming, and at the same time a night, i.e., that even if the morning dawns, it will be swallowed up again directly by night. And the history was quite in accordance with such an answer. The Assyrian period of judgment was followed by the Chaldean, and the Chaldean by the Persian, and the Persian by the Grecian, and the Grecian by the Roman. Again and again there was a glimmer of morning dawn for Edom (and what a glimmer in the Herodian age!), but it was swallowed up directly by another night, until Edom became an utter Dūmâh, and disappeared from the history of the nations. The prophet does not see to the utmost end of these Edomitish nights, but he has also no consolation for Edom. It is altogether different with Edom from what it is with Israel, the nocturnal portion of whose history has a morning dawn, according to promise, as its irrevocable close. The prophet therefore sends the inquirers home. Would they ask any further questions, they might do so, might turn and come. In shūbū (turn back) there lies a significant though ambiguous hint. It is only in the case of their turning, coming, i.e., coming back converted, that the prophet has any consolatory answer for them. So long as they are not so, there is suspended over their future an interminable night, to the prophet as much as to themselves. The way to salvation for every other people is just the same as for Israel - namely, the way of repentance.

The night - The night is past without any mischief, and the light of the morning is approaching; but tho' the morning is coming, it will be gone, and the night will return, and your fears with it. Come - If you will enquire, enquire: I perceive your danger is not past, and there will be occasion for farther enquiries. Therefore return, come - Come to me the next morning, and so from morning to morning.
