Deuteronomy 12:23-27

Only be sure not to eat the blood, for the blood is the life, and you shall not eat the life with the flesh.

You shall not eat it; you shall pour it out on the ground like water.

You shall not eat it, so that it may go well for you and your sons after you, since you will be doing what is right in the sight of the Lord.

Only your holy things which you may have and your vowed offerings, you shall take and go to the place which the Lord chooses.

And you shall offer your burnt offerings, the flesh and the blood, on the altar of the Lord your God; and the blood of your sacrifices shall be poured out on the altar of the Lord your God, and you shall eat the flesh.
