And if he does not live near you and you do not know who he is, you shall bring it home to your house, and it shall stay with you until your brother seeks it. Then you shall restore it to him. And you shall do the same with his donkey or with his garment, or with any lost thing of your brother's, which he loses and you find; you may not ignore it.
