Deuteronomy 10:17-21

For the LORD your God is God of gods and Lord of lords, the great God, mighty and awesome, who is not partial and takes no bribe, who executes justice for the orphan and the widow, and who loves the strangers, providing them food and clothing. You shall also love the stranger, for you were strangers in the land of Egypt. You shall fear the LORD your God; him alone you shall worship; to him you shall hold fast, and by his name you shall swear. He is your praise; he is your God, who has done for you these great and awesome things that your own eyes have seen.
