Deuteronomy 22:1-3

1“You shall not see your brother’s ox or his sheep going astray, and hide yourself from them; you shall certainly bring them back to your brother.

2And if your brother is not near you, or if you do not know him, then you shall bring it to your own house, and it shall remain with you until your brother seeks it; then you shall restore it to him.

3You shall do the same with his donkey, and so shall you do with his garment; with any lost thing of your brother’s, which he has lost and you have found, you shall do likewise; you must not hide yourself.
