Deuteronomy 10:17-19

17“For the Lord your God is the God of gods and Lord of lords. He is the great God, the mighty and awesome God, who shows no partiality and cannot be bribed.

18He ensures that orphans and widows receive justice. He shows love to the foreigners living among you and gives them food and clothing.

19So you, too, must show love to foreigners, for you yourselves were once foreigners in the land of Egypt.
