Moses
Deuteronomy 22:3BSB·traditional attribution

And you shall do the same for his donkey, his cloak, or anything your brother has lost and you have found. You must not ignore it.

Matthew Henry Presbyterian @wholebiblehenry

The kindness that was commanded to be shown in reference to an enemy (Exo 23:4, etc.) is here required to be much more done for a neighbour, though he were not an Israelite, for the law is consonant to natural equity. 1. That strayed cattle should be brought back, either to the owner or to the pasture out of which they had gone astray, Deu 22:1, Deu 22:2.

John Gill Reformed Baptist @doctorgill

In like manner shall thou do with his ass,.... As with his ox or sheep when astray, and found, keep it until it is owned, and then restore it; this is expressly mentioned in Exo 23:4. and so shalt thou do with his raiment; if that is lost and found, it must be restored to the owner, he describing it; a garment is particularly mentioned...

Geneva Bible Notes Reformed @genevanotes

In like manner shalt thou do with his ass; and so shalt thou do with his raiment; and with all lost thing of thy brother's, which he hath lost, and thou hast found, shalt thou do likewise: thou mayest not hide thyself. (c) You are bound to do much more for your neighbour.
