Deuteronomy 22:2-4

Amplified Bible

² If your countryman is not nearby or you do not know him, you shall bring the animal to your house, and it shall stay with you until he searches for it; then you shall return it to him. ³ You shall do this with his donkey or with his garment or with anything that your countryman has lost and you have found. You are not allowed to ignore [your duty to help] them. ⁴ You shall not see your countryman’s donkey or his ox fall down along the road, and ignore [your duty to help] them; you shall certainly help him lift it up.
