Numbers 18:5

In the tabernacle of the congregation without the vail, which is before the testimony, Aaron and his sons shall order it from evening to morning before the Lord: it shall be a statute for ever unto their generations on the behalf of the children of Israel.

Without the vail of the testimony, in the tabernacle of the congregation, shall Aaron order it from the evening unto the morning before the Lord continually: it shall be a statute for ever in your generations.

And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the Lord; the plague is begun.

Thus were they divided by lot, one sort with another; for the governors of the sanctuary, and governors of the house of God, were of the sons of Eleazar, and of the sons of Ithamar.

And Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, of the house of his father, the Korahites, were over the work of the service, keepers of the gates of the tabernacle: and their fathers, being over the host of the Lord, were keepers of the entry.

So they and their children had the oversight of the gates of the house of the Lord, namely, the house of the tabernacle, by wards.

And these are the singers, chief of the fathers of the Levites, who remaining in the chambers were free: for they were employed in that work day and night.

This charge I commit unto thee, son Timothy, according to the prophecies which went before on thee, that thou by them mightest war a good warfare;

But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.

I charge thee before God, and the Lord Jesus Christ, and the elect angels, that thou observe these things without preferring one before another, doing nothing by partiality.

O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:

And Aaron shall burn thereon sweet incense every morning: when he dresseth the lamps, he shall burn incense upon it. And when Aaron lighteth the lamps at even, he shall burn incense upon it, a perpetual incense before the Lord throughout your generations. Ye shall offer no strange incense thereon, nor burnt sacrifice, nor meat offering; neither shall ye pour drink offering thereon. And Aaron shall make an atonement upon the horns of it once in a year with the blood of the sin offering of atonements: once in the year shall he make atonement upon it throughout your generations: it is most holy unto the Lord.

Therefore thus saith the Lord of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land.

And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Uncover not your heads, neither rend your clothes; lest ye die, and lest wrath come upon all the people: but let your brethren, the whole house of Israel, bewail the burning which the Lord hath kindled.

And I 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 tabernacle of the congregation, and to make an atonement for the children of Israel: that there be no plague among the children of Israel, when the children of Israel come nigh unto the sanctuary.

Speak unto Aaron, and say unto him, When thou lightest the lamps, the seven lamps shall give light over against the candlestick.

Mine anger was kindled against the shepherds, and I punished the goats: for the Lord of hosts hath visited his flock the house of Judah, and hath made them as his goodly horse in the battle.
