Deuteronomy 12:18 (KJV)

Only ye shall not eat the blood; ye shall pour it upon the earth as water.

Thou mayest not eat within thy gates the tithe of thy corn, or of thy wine, or of thy oil, or the firstlings of thy herds or of thy flock, nor any of thy vows which thou vowest, nor thy freewill offerings, or heave offering of thine hand:

But thou must eat them before the Lord thy God in the place which the Lord thy God shall choose, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates: and thou shalt rejoice before the Lord thy God in all that thou puttest thine hands unto.

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

When the Lord thy God shall enlarge thy border, as he hath promised thee, and thou shalt say, I will eat flesh, because thy soul longeth to eat flesh; thou mayest eat flesh, whatsoever thy soul lusteth after.
