And thou shalt take of the blood thereof, and put it on the four horns of it, and on the four corners of the ledge, and upon the border round about: thus shalt thou cleanse it and make atonement for it.
And the priest shall take of the blood of the sin-offering, and put it upon the door-posts of the house, and upon the four corners of the ledge of the altar, and upon the posts of the gate of the inner court.
