Deuteronomy 10:19

17For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:

18He doth execute the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment.

19Love ye therefore the stranger: for ye were strangers in the land of Egypt.

20Thou shalt fear the LORD thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name.

21He is thy praise, and he is thy God, that hath done for thee these great and terrible things, which thine eyes have seen.
