Leviticus 1:5

And he shall kill the bullock - Tradition states that before the laying on of the hand, the victim was bound by a cord to a ring on the north side of the altar; as the words of the prayer were ended, the throat was cut and the blood received into a bowl held by an assistant.

Sprinkle the blood - Rather, throw the blood, so as to make the liquid cover a considerable surface. (The Christian significance of this typical action is referred to in Hebrews 12:24; 1 Peter 1:2.)

By the door of the tabernacle - At the entrance of the tent.
