Leviticus

For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.

And the priest shall put some of the blood upon the horns of the altar of sweet incense before the Lord, which is in the tabernacle of the congregation; and shall pour all the blood of the bullock at the bottom of the altar of the burnt offering, which is at the door of the tabernacle of the congregation.

Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry.

And thou shalt take of the blood of the bullock, and put it upon the horns of the altar with thy finger, and pour all the blood beside the bottom of the altar.

And thou shalt take of the blood thereof, and put it on the four horns of it, and on the four corners of the settle, and upon the border round about: thus shalt thou cleanse and purge it.
