Leviticus 19:18, 34

Thou shalt not take vengeance, nor bear any grudge against the children of thy people; but thou shalt love thy neighbor as thyself: I am Jehovah.

The stranger that sojourneth with you shall be unto you as the home-born among you, and thou shalt love him as thyself; for ye were sojourners in the land of Egypt: I am Jehovah your God.
