¹⁸ Then he said to me: Mortal, thus says the Lord God: These are the ordinances for the altar: On the day when it is erected for offering burnt offerings upon it and for dashing blood against it, ¹⁹ you shall give to the levitical priests of the family of Zadok, who draw near to me to minister to me, says the Lord God, a bull for a sin offering.
