18 He said to me, Human one, the Lord God proclaims: These are the regulations established for the altar on the day when it is prepared for making entirely burned offerings and dashing blood on it.
19 You will provide a young bull as a purification offering to the levitical priests who are descendants of Zadok, the ones who may draw near to minster to me. This is what the Lord God says.
