Exodus 29:10-12

LXX2012(i) 10 And you shall bring the calf to the door of the tabernacle of witness; and Aaron and his sons shall lay their hands on the head of the calf, before the Lord, by the doors of the tabernacle of witness. 11 And you shall kill the calf before the Lord, by the doors of the tabernacle of witness. 12 And you shall take of the blood of the calf, and put it on the horns of the altar with your finger, but all the rest of the blood you shall pour out at the foot of the altar.
