Deuteronomy 10:17-19

For Jehovah your God, he is God of gods, and Lord of lords, the great God, the mighty, and the terrible, who regardeth not persons, nor taketh reward. He doth execute justice for the fatherless and widow, and loveth the sojourner, in giving him food and raiment. Love ye therefore the sojourner; for ye were sojourners in the land of Egypt.
