1 Chronicles 15:12

⁶Kill the Passover lamb, sanctify yourselves, and prepare for your brothers, to do according to the LORD’s word by Moses.”

¹⁴Moses went down from the mountain to the people, and sanctified the people; and they washed their clothes. ¹⁵He said to the people, “Be ready by the third day. Don’t have sexual relations with a woman.”

¹⁴So the priests and the Levites sanctified themselves to bring up the ark of the LORD, the God of Israel.

¹Therefore I urge you, brothers, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service. ²Don’t be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.

¹⁵Then they killed the Passover on the fourteenth day of the second month. The priests and the Levites were ashamed, and sanctified themselves, and brought burnt offerings into the LORD’s house.

¹⁷Sanctify them in your truth. Your word is truth.

¹David made himself houses in David’s city; and he prepared a place for God’s ark, and pitched a tent for it.

¹¹It shall be for the priests who are sanctified of the sons of Zadok, who have kept my instruction, who didn’t go astray when the children of Israel went astray, as the Levites went astray.

³⁴These were heads of fathers’ households of the Levites, throughout their generations, chief men. They lived at Jerusalem.

⁴He brought in the priests and the Levites and gathered them together into the wide place on the east, ⁵and said to them, “Listen to me, you Levites! Now sanctify yourselves, and sanctify the house of the LORD, the God of your fathers, and carry the filthiness out of the holy place.
