1You shall not see your brother`s ox or his sheep go astray, and hide yourself from them: you shall surely bring them again to your brother. 2If your brother isn`t near to you, or if you don`t know him, then you shall bring it home to your house, and it shall be with you until your brother seek after it, and you shall restore it to him. 3So shall you do with his donkey; and so shall you do with his garment; and so shall you do with every lost thing of your brother`s, which he has lost, and you have found: you may not hide yourself. 4You shall not see your brother`s donkey or his ox fallen down by the way, and hide yourself from them: you shall surely help him to lift them up again.
