and I brought them into Yahweh’s house, into the room of the sons of Hanan the son of Igdaliah, the man of God, which was by the room of the princes, which was above the room of Maaseiah the son of Shallum, the keeper of the threshold.

These are the names of the sons of Aaron: Nadab the firstborn, and Abihu, Eleazar, and Ithamar.

For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit.

Yahweh said to Moses, “Go to the people, and sanctify them today and tomorrow, and let them wash their garments,

“Bring Aaron your brother, and his sons with him, near to you from among the children of Israel, that he may minister to me in the priest’s office: Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

This is the blessing with which Moses the man of God blessed the children of Israel before his death.

and with them Heman and Jeduthun with trumpets and cymbals for those that should sound aloud, and with instruments for the songs of God; and the sons of Jeduthun to be at the gate.

four thousand were doorkeepers, and four thousand praised Yahweh with the instruments which I made for giving praise.”

These were the divisions of the sons of Aaron. The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar.

Eastward were six Levites, northward four a day, southward four a day, and for the storehouse two and two.

“All this”, David said, “I have been made to understand in writing from Yahweh’s hand, even all the works of this pattern.”

This is the thing that you must do. A third part of you, who come in on the Sabbath, of the priests and of the Levites, shall be gatekeepers of the thresholds.

and said to them, “Listen to me, you Levites! Now sanctify yourselves, and sanctify Yahweh, the God of your fathers’ house, and carry the filthiness out of the holy place.

They gathered their brothers, sanctified themselves, and went in, according to the commandment of the king by Yahweh’s words, to cleanse Yahweh’s house.

But the priests were too few, so that they could not skin all the burnt offerings. Therefore their brothers the Levites helped them, until the work was ended, and until the priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests.

Then 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 Yahweh’s house.

Hezekiah appointed the divisions of the priests and the Levites after their divisions, every man according to his service, both the priests and the Levites, for burnt offerings and for peace offerings, to minister, to give thanks, and to praise in the gates of Yahweh’s camp.
