  Thou shalt rise up before the hoary head, and honor the face of the old man, and fear thy God: I am the LORD. 
 And if a stranger sojourn with thee in your land, ye shall not vex him.
  But the stranger that dwelleth with you shall be unto you as one born among you, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the LORD your God.

  For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:
 18  He doth execute the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment.
 19  Love ye therefore the stranger: for ye were strangers in the land of Egypt.
 20  Thou shalt fear the LORD thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name.
 21  He is thy praise, and he is thy God
