2 If your fellow Israelite is not close by or you don't know whose it is, take the animal home with you and take care of it until your fellow asks about it. Then return 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.
