Numbers 18:5

²¹In the Tent of Meeting, outside the veil which is before the covenant, Aaron and his sons shall keep it in order from evening to morning before the LORD: it shall be a statute forever throughout their generations on the behalf of the children of Israel.

⁴⁶Moses said to Aaron, “Take your censer, put fire from the altar in it, lay incense on it, carry it quickly to the congregation, and make atonement for them; for wrath has gone out from the LORD! The plague has begun.”

³Outside of the veil of the Testimony, in the Tent of Meeting, Aaron shall keep it in order from evening to morning before the LORD continually. It shall be a statute forever throughout your generations.

⁶Moses said to Aaron, and to Eleazar and to Ithamar, his sons, “Don’t let the hair of your heads go loose, and don’t tear your clothes, so that you don’t die, and so that he will not be angry with all the congregation; but let your brothers, the whole house of Israel, bewail the burning which the LORD has kindled.

⁵Thus they were divided impartially by drawing lots; for there were princes of the sanctuary and princes of God, both of the sons of Eleazar, and of the sons of Ithamar.

¹⁸I commit this instruction to you, my child Timothy, according to the prophecies which were given to you before, that by them you may wage the good warfare,

¹⁹Shallum was the son of Kore, the son of Ebiasaph, the son of Korah, and his brothers, of his father’s house, the Korahites, were over the work of the service, keepers of the thresholds of the tent. Their fathers had been over the LORD’s camp, keepers of the entry.

²¹I command you in the sight of God, and the Lord Jesus Christ, and the chosen angels, that you observe these things without prejudice, doing nothing by partiality.

¹⁵Therefore the LORD of Armies says concerning the prophets: “Behold, I will feed them with wormwood, and make them drink poisoned water; for from the prophets of Jerusalem ungodliness has gone out into all the land.”

¹⁹I have given the Levites as a gift to Aaron and to his sons from among the children of Israel, to do the service of the children of Israel in the Tent of Meeting, and to make atonement for the children of Israel, so that there will be no plague among the children of Israel when the children of Israel come near to the sanctuary.”
