Deuteronomy 22:2-4 New International Version - UK (NIVUK)
2 If they do not live near you or if you do not know who owns it, take it home with you and keep it until they come looking for it. Then give it back. 3 Do the same if you find their donkey or cloak or anything else they have lost. Do not ignore it.
4 If you see your fellow Israelite’s donkey or ox fallen on the road, do not ignore it. Help the owner to get it to its feet.
