Deuteronomy 22:2-4

New Revised Standard Version Catholic Edition

² If the owner does not reside near you or you do not know who the owner is, you shall bring it to your own house, and it shall remain with you until the owner claims it; then you shall return it. ³ You shall do the same with a neighbor’s donkey; you shall do the same with a neighbor’s garment; and you shall do the same with anything else that your neighbor loses and you find. You may not withhold your help.

⁴ You shall not see your neighbor’s donkey or ox fallen on the road and ignore it; you shall help to lift it up.
