Deuteronomy 10:17-19

17For the LORD your God is God of gods and Lord of lords, the great God, mighty and awesome, who shows no partiality and accepts no bribes. 18He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. 19And you are to love those who are foreigners, for you yourselves were foreigners in Egypt.
