They have dealt treacherously - Literally, "have cloaked," and so, acted deceitfully. The word is used of treachery of friend toward his friend, of the husband to his wife, or the wife husband. "Surely as a wife treacherously departeth from her husband, so have ye dealt treacherously with Me, O house of Israel, saith the Lord" Jeremiah 3:20. God, even in His upbraiding, speaks very tenderly to them, as having been in the closest, dearest relation to Himself.

For they have begotten strange children - God had made it a ground of the future blessing of Abraham, "I know him, that he will command his children and his household after him, and they shall keep the way of the Lord, to do justice and judgment" Genesis 18:19. But these, contrariwise, themselves being idolaters and estranged from God, had children, who fell away like themselves, strangers to God, and looked upon as strangers by Him. The children too of the forbidden marriages with the pagan were, by their birth, strange or foreign children, even before they became so in act; and they became so the more in act, because they were so by birth. The next generation then growing up more estranged from God than themselves, what hope of amendment was there?

Now shall a month devour - The word now denotes the nearness and suddenness of God's judgments; the term "month," their rapidity. A "month" is not only a brief time, but is almost visibly passing away; the moon, which measures it, is never at one stay, waxing until it is full, then waning until it disappears. Night by night bears witness to the month's decay. The iniquity was full; the harvest was ripe; "now," suddenly, rapidly, completely, the end should come. One month should "devour them with their portions." God willed to be the Portion of His people; He had said, "the Lord's portion is His people; Jacob is the lot of His inheritance" Deuteronomy 32:9. To Himself He had given the title, "the protion of Jacob" Jeremiah 10:16. Israel had chosen to himself "other portions" out of God, for these, he had forsaken his God; therefore he should be consumed with them. "All that they had, all that they possessed, enjoyed, trusted in, all, at once, shall that short space, suddenly and certainly to come; devour, deprive and bereave them of; none of them shall remain with them or profit them in the day of wrath."

Now shall a month devour them - In a month's time the king of Assyria shall be upon them, and oblige them to purchase their lives and liberties by a grievous tax of fifty shekels per head. This Menahem, king of Israel, gave to Pul, king of Assyria, 2 Kings 15:16-20. Instead of month, some translate the original locust. "The locusts shall devour them."

They have dealt treacherously against the Lord,.... Which was the reason of his departure from them; as a woman deals treacherously with her husband when she is unfaithful to him, and commits adultery; so Israel and Judah dealt treacherously with the Lord, who stood in the relation of a husband to them in covenant, by committing idolatry;

for they have begotten strange children; either of strange women, the daughters of idolatrous Heathens they married, so the Targum, Jarchi, and Kimchi; or rather their natural children, though born of Israelitish or Jewish parents, both such; yet being educated by them in an idolatrous way, and brought up in the commission of the evils their parents were guilty of, are said to be strange children to the Lord, alienated from him and his worship, and as such to be begotten:

now shall a month devour them with their portions; the Jews understand this literally of the month Ab, the time of Jerusalem's destruction, so Jarchi and R. Jeshuah in Aben Ezra and Ben Melech; or the month Tammuz, in which the city was broke up, and the month Ab, in which it was destroyed, as Kimchi; or rather, which is also a sense he mentions, it signifies a short time, a very little while before the destruction should come; and compares it with Zechariah 11:8; though, according to the Targum, it is to be understood of every month; and so denotes the continual desolation that should be made, until they were utterly destroyed; but others seem better to interpret it of their new moon, or first day of the month, which they observed in a religious way, by offering sacrifice, &c. and on which they depended; but this should be so far from being of any service to them, that it should turn against them; and, because of the idolatry committed in them, the Lord would hate them, and destroy them on account of them; even their farms, and fields, and vineyards, which were their portions and inheritances; see Isaiah 1:13; unless it is rather to be understood of the parts of the beasts slain in sacrifice on those days, to appease the Lord; which would be so far from doing it, that they would provoke him yet more to wrath, and slay them.

They have dealt treacherously against the LORD: for they have begotten {f} strange children: now shall {g} a month devour them with their portions.

(f) That is, their children are degenerate, so that there is no hope in them.

(g) Their destruction is not far off.

5:7 Have begotten - They have trained up their children in the same idolatry. A month - Possibly it may refer to Shallum's short time of usurpation, which lasted but a month; the Assyrians shall make a speedy conquest over you. With their portions - With all their substance.

7. treacherously-as to the marriage covenant (Jer 3:20).

strange children-alluding to "children of whoredoms" (Ho 1:2; 2:4). "Strange" or foreign implies that their idolatry was imported from abroad [Henderson]. Or rather, "regarded by God as strangers, not His," as being reared in idolatry. The case is desperate, when not only the existing, but also the rising, generation is reared in apostasy.

a month-a very brief space of time shall elapse, and then punishment shall overtake them (Zec 11:8). The allusion seems to be to money loans, which were by the month, not as with us by the year. You cannot put it off; the time of your destruction is immediately and suddenly coming on you; just as the debtor must meet the creditor's demand at the expiration of the month. The prediction is of the invasion of Tiglath-pileser, who carried away Reuben, Gad, Naphtali, and the half tribe of Manasseh.

portions-that is, possessions. Their resources and garrisons will not avail to save them. Henderson explains from Isa 57:6, "portions" as their idols; the context favors this, "the Lord" the true "portion of His people" (De 32:9), being in antithesis to "their portions," the idols.

5:1-7 The piercing eye of God saw secret liking and disposition to sin, the love the house of Israel had to their sins, and the dominion their sins had over them. Pride makes men obstinate in other sins. And as Judah was treading in the same steps, they would fall with Israel. By dealing treacherously with the Lord, men only deceive themselves. Those that go to seek the Lord with their flocks and their herds only, and not with their hearts and souls, cannot expect to find him; nor shall any speed who do not seek the Lord while he may be found. See how much it is our concern to seek God early, now, while it is the accepted time, and the day of salvation.
