Deuteronomy 24:10-13

(10-13) When thou dost lend. — The law in these verses is evidently the production of primitive and simple times, when men had little more than the bare necessaries of life to offer as security — their own clothing, or the mill-stones used to prepare their daily food, being almost their only portable property. (See Exodus 22:26.)

It shall be righteousness. — LXX., it shall be alms, or mercy. In other words, “Blessed are the merciful, for they shall obtain mercy.”
