Deuteronomy 22:1-3

“You shall not see your countryman’s ox or his sheep straying away or being stolen, and ignore [your duty to help] them; you shall certainly take them back to him. [Prov 24:12] 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. 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.
