Deuteronomy 12:12, 19

and ye shall rejoice before the LORD your God, ye, and your sons, and your daughters, and your menservants, and your maidservants, and the Levite that is within your gates; forasmuch as he hath no part nor inheritance with you.

Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.
