Leviticus 19:33-34

"When strangers sojourn with you in your land, you shall do them no wrong, the strangers who sojourn with you shall be to you as natives among you, and you love them as yourself; for you were strangers in the land of Egypt."

Levtitcus is the third book of the Hebrew Bible (sometimes called the Old Testament) and the third of five books of the Torah (or Pentateuch).
