“Then shall he kill the goat of the purification for sin offering, which is for the people, and bring his blood within the veil, and do with his blood as he did with the blood of the bull ox, and sprinkle it on the mercy-seat, and before the mercy-seat,”
His third entry into the Holy of Holies on that Day is after the killing of the he-goat for a purification for sin offering on behalf of the people. He also brings that blood within the veil and deals with it in the same way as with the blood of the bull ox.
