2 And if thy brother be not nigh unto thee, or if thou know him not, then thou shalt bring it home to thy house, and it shall be with thee until thy brother seek after it, and thou shalt restore it to him.

Matthew Henry's Commentary on Deuteronomy 22:2

Commentary on Deuteronomy 22:1-4

(Read Deuteronomy 22:1-4)

If we duly regard the golden rule of "doing to others as we would they should do unto us," many particular precepts might be omitted. We can have no property in any thing that we find. Religion teaches us to be neighbourly, and to be ready to do all good offices to all men. We know not how soon we may have occasion for help.
