Deuteronomy 22:2-4 Common English Bible (CEB)
2 If the owner doesn’t live nearby, or you don’t know who owns the animal, then you must take care of it. It should stay with you until your fellow Israelite comes looking for it, at which point you must return it to him.
3 Do the same thing in the case of a donkey. Do the same thing in the case of a piece of clothing. Do the same thing in the case of anything that your fellow Israelite loses and you end up finding. You are not allowed to sit back and do nothing about it.
4 Don’t just watch your fellow Israelite’s donkey or ox fall down in the road and do nothing about it. You must help your fellow Israelite get the animal up again.
