Deuteronomy 22:1-4

1 You shall not see your brother's ox or his sheep go astray, and hide yourself from them: you shall in any case bring them again to your brother.

2 And if your brother be not near to you, or if you know him not, then you shall bring it to your own house, and it shall be with you until your brother seek after it, and you shall restore it to him again.

3 In like manner shall you do with his ass; and so shall you do with his raiment; and with all lost thing of your brother's, which he has lost, and you have found, shall you do likewise: you may not hide yourself.

4 You shall not see your brother's ass or his ox fall down by the way, and hide yourself from them: you shall surely help him to lift them up again.
