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.

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.
