Deuteronomy 12:23-25

Only be sure that thou eat not the blood: for the blood is the life; and thou mayest not eat the life with the flesh.

Thou shalt not eat it; thou shalt pour it upon the earth as water.

Thou shalt not eat it; that it may go well with thee, and with thy children after thee, when thou shalt do that which is right in the sight of the LORD.
