Deuteronomy 23:20 Meaning and Commentary

Deuteronomy 23:20

Unto a stranger thou mayest lend upon usury
To any Gentile, though some Jewish writers except the Edomites and Ishmaelites, as being brethren, and restrain it to the seven nations of Canaan; but it seems to design one that was not an Israelite, or a proselyte of righteousness, and especially to regard such that traded and merchandised, as the Gentiles very much did, and especially their neighbours the Phoenicians; and of such it was lawful to take interest, as it was but reasonable, when they gained much by the money they lent them, and as it is but reasonable should be the case among Christians in such circumstances; this is to be regarded not as a precept, but as a permission:

but unto thy brother thou shalt not lend upon usury;
which is repeated, that it might be taken notice of, and carefully observed:

that the Lord thy God may bless thee in all that thou settest thine
hand unto, in the land whither thou goest to possess it;
for their charity, humanity, and the kind usage of their poor brethren in distress, would not pass unnoticed by the Lord; but he would make the land they tilled fruitful, and their vineyards and oliveyards to produce abundance, and their flocks and their herds to increase greatly, which would be sufficient and more than a recompence for all that they had freely lent unto their brethren, without taking any usury of them.

Deuteronomy 23:20 In-Context

18 You shall not bring the hire of a harlot, or the wages of a dog, into the house of the LORD your God in payment for any vow; for both of these are an abomination to the LORD your God.
19 "You shall not lend upon interest to your brother, interest on money, interest on victuals, interest on anything that is lent for interest
20 To a foreigner you may lend upon interest, but to your brother you shall not lend upon interest; that the LORD your God may bless you in all that you undertake in the land which you are entering to take possession of it.
21 "When you make a vow to the LORD your God, you shall not be slack to pay it; for the LORD your God will surely require it of you, and it would be sin in you
22 But if you refrain from vowing, it shall be no sin in you.
