Deuteronomy 10:16-19

Give yourselves completely to serving him, and do not be stubborn any longer. The LORD your God is God of all gods and Lord of all lords. He is the great God, who is strong and wonderful. He does not take sides, and he will not be talked into doing evil. He helps orphans and widows, and he loves foreigners and gives them food and clothes. You also must love foreigners, because you were foreigners in Egypt.
