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 22:26-27.)

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