The Prophet no doubt wished to strip the Jews of their vain confidence, through which they acted arrogantly and presumptuously towards God, while yet they professed his name and claimed his favor. They said that they had obtained that land by an hereditary right, because it had been promised to their father Abraham. This indeed was true. They also said, that the land was God’s rest; and they derived this from the prophets. They said farther that God was their heritage; and this also was true. But since they had wickedly profaned God’s name, he takes from them these false boastings, and says, This is thy lot But still they said, When God divided the nations, his lot fell on Israel, for so says Moses. (Deuteronomy 32:8) As then they were wont to say, that God afterwards deceived them, the Prophet here on the other hand reminds them, that they foolishly confided in that lot, because God had rejected them, and did not acknowledge them now as his children, as they were become degenerate and perfidious. This, he says, is thy lot ⁹⁸⁹⁸     It may be thus rendered, —
   This thy lot is the share of thy measures From me, saith Jehovah.
   The “lot” was the scattering threatened in the previous verse. “The share of thy measures,” is a Hebrew idiom for “a measured share,” or “a measured portion,” as rendered by Blayney. Some say that “measures” are mentioned, because the length and breadth were included. — Ed.

We see that there is to be understood here a contrast: God was the lot of the people, and they were also the lot of God, according to the passages to which we have referred. They were the heritage of God, and they boasted that God was their heritage; the land was a symbol and a pledge of this heritage. The Prophet now says: “This lot shall be to thee the portion of thy measures from me.” He alludes to an ancient custom; for they were wont to divide fields and meadows by lines, as they afterwards used poles; and we call such measures in the present day perches (perticas.)

We now then understand what the Prophet means; for he intimates that the Jews vainly and presumptuously and foolishly boasted, that God was their heritage; for he owned them not now as his children: and he also declares that another lot was prepared for them, far different from that of heritage, — that God would banish them from the promised land, which they had polluted by their vices. Thus we see that we ought not presumptuously and falsely to pretend or profess the name of God; for though he has been pleased to choose us as his people, it is yet required of us to be faithful to him; and if we forsake him, the same reward for our impiety will no doubt await us as Jeremiah threatens here to his own nation. Let us then so use the favor of God and of Christ, and all the blessings which are offered to us by the gospel, that we may not have to fear that vengeance which happened to the Jews.

He adds the reason, Because thou hast forgotten me and trusted in falsehood ⁹⁹⁹⁹     It is better to render אשר here “because” or for, according to all the versions and the Targum, than “who,” as by Blayney. — Ed. By falsehood the Prophet means not only the superstitions in which the Jews involved themselves, but also the false counsels which they adopted, when at one time they had recourse to the Egyptians, at another to some other ungodly nations, in order to get aids in opposition to the will of God. For wherever there was any danger, they thought they had a remedy at hand by having the favor and help of the Egyptians, or of the Assyrians, or of the Chaldeans. In the word falsehood, then, the Prophet includes those perverse designs which they formed, when they sought to defend themselves against God, who would have protected them by his power, had it not been necessary to punish them for their sins. What Jeremiah then condemned in the people was, that they placed their trust in falsehood, that is, that they souglint here and there vain helps, and at the same time disregarded God; nay, they thought themselves safer when God was displeased with them: and hence he says, Thou hast forgotten me For the Jews could not have sought deliverance from the Egyptians or from other heathen nations, or from their idols, without having first rejected God; for if this truth had been really fixed in their minds, — that God cared for their safety, they would no doubt have been satisfied with his protection. Their ingratitude was therefore very manifest in thus adopting vain and impious hopes; for they thus dishonored God, and distrusted his power, as though he was not sufficient to preserve them. It now follows—
