He shall lend to thee, and thou shall not lend to him,.... The stranger, or one of another nation, shall be in a capacity of lending to the Jew, when the Jew would not be able to lend to the Gentile, his circumstances being so low and mean; to show which is the design of the expression, and not the kindness or unkindness of either; see Deuteronomy 28:12,

he shall be the head, and thou shalt be the tail; he shall be ruler and governor, and thou shalt be subject to him; see Deuteronomy 28:13.

The opposite of Deuteronomy 28:12 and Deuteronomy 28:13 would come to pass. - In Deuteronomy 28:46 the address returns to its commencement in Deuteronomy 28:15, with the terrible threat, "These curses shall be upon thee for a sign and for a wonder, and upon thy seed for ever," for the purpose of making a pause, if not of bringing the whole to a close. The curses were for a sign and wonder (מופת, that which excites astonishment and terror), inasmuch as their magnitude and terrible character manifested most clearly the supernatural interposition of God (vid., Deuteronomy 29:23). "For ever" applies to the generation smitten by the curse, which would remain for ever rejected, though without involving the perpetual rejection of the whole nation, or the impossibility of the conversion and restoration of a remnant, or of a holy seed (Isaiah 10:22; Isaiah 6:13; Romans 9:27; Romans 11:5).

He shall lend to thee, and thou shalt not lend to him: he shall be the head, and thou shalt be the tail.

28:15-44 If we do not keep God's commandments, we not only come short of the blessing promised, but we lay ourselves under the curse, which includes all misery, as the blessing all happiness. Observe the justice of this curse. It is not a curse causeless, or for some light cause. The extent and power of this curse. Wherever the sinner goes, the curse of God follows; wherever he is, it rests upon him. Whatever he has is under a curse. All his enjoyments are made bitter; he cannot take any true comfort in them, for the wrath of God mixes itself with them. Many judgments are here stated, which would be the fruits of the curse, and with which God would punish the people of the Jews, for their apostacy and disobedience. We may observe the fulfilling of these threatenings in their present state. To complete their misery, it is threatened that by these troubles they should be bereaved of all comfort and hope, and left to utter despair. Those who walk by sight, and not by faith, are in danger of losing reason itself, when every thing about them looks frightful.
