Exodus 22:25

And such provision the law made for the preserving estates to their families by the year of Jubilee, that a people who had little concern in trade could not be supposed to borrow money but for necessity; therefore it was generally forbidden among themselves; but to a stranger they were allowed to lend upon usury.

If we were not able to make restitution, he must be sold for a slave: the court of judgment was to do it, and it is likely the person robbed received the money. Thus with us in some cases, felons are transported to the Plantations, where only, Englishmen know what slavery is.

If thou lend money to any of my people that is poor by thee, Such only need to borrow money, and to whom it should be freely lent, when it may be to the good of the borrower, and not any injury to the lender: this law, according to the Jewish writers, only respects Israelites, and not Gentiles; agreeably to which is Jarchi's note,"if thou lend, that is, not to a Gentile; and to which of my people? the poor, and to which of the poor? that is with thee:" thou shalt not be to him as an usurer; that will not lend without usury, nor without an exorbitant interest, and deals very hardly with the borrower if he is not punctual in the payment of it; the Israelites were not only not to be usurers, but they were not to be like them; they were not to require anything for lending a poor man a little money; as not any settled interest, so neither were they to take any previous gift or reward later, see Luk 6:34. neither shalt thou lay upon him usury; or oblige him to give interest for money borrowed: it is in the plural, number, "neither shall ye lay"; and Aben Ezra observes, that the lender, scribe, and witness, all transgress this law; that is, when a man lends money on interest, and a bond is made by the scribe for it, and this signed by witnesses, all are guilty of the breach of it: yea, some Jewish writers (h) say, not only those, but whoever is a surety or bondsman for the payment, and even the borrower himself; see Gill on Psa 15:5. (h) Misn. Bava Metzia, c. 5. sect. 11. Maimon. & Bartenora in ib.

Neither shalt thou lay upon him usury - נשך neshech, from nashach, to bite, cut, or pierce with the teeth; biting usury. So the Latins call it usura vorax, devouring usury. “The increase of usury is called נשך neshech, because it resembles the biting of a serpent; for as this is so small as scarcely to be perceptible at first, but the venom soon spreads and diffuses itself till it reaches the vitals, so the increase of usury, which at first is not perceived nor felt, at length grows so much as by degrees to devour another’s substance.” - Leigh.
