Deuteronomy 12:26-27

LXX2012(i) 26 But you shall take your holy things, if you have any, and your vowed-offerings, and come to the place which the Lord your God shall choose to have his name named upon it. 27 And you shall sacrifice your whole burnt offerings, you shall offer the flesh upon the altar of the Lord your God; but the blood of your sacrifices you shall pour out at the foot of the altar of the Lord your God, but the flesh you shall eat.
