'Levitical' in the Bible

You shall give to the Levitical priests who are from the offspring of Zadok, who draw near to Me to minister to Me,’ declares the Lord God, ‘a young bull for a sin offering.

“But the Levitical priests, the sons of Zadok, who kept charge of My sanctuary when the sons of Israel went astray from Me, shall come near to Me to minister to Me; and they shall stand before Me to offer Me the fat and the blood,” declares the Lord God.
