TSK · Numbers 18:5

And Aaron shall burn thereon sweet incense every morning: when he dresseth the lamps, he shall burn incense upon it.

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.

Cut ye not off the tribe of the families of the Kohathites from among the Levites:

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.

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.

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.

And that they should keep the charge of the tabernacle of the congregation, and the charge of the holy [place], and the charge of the sons of Aaron their brethren, in the service of the house of 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.

They shall enter into my sanctuary, and they shall come near to my table, to minister unto me, and they shall keep my charge.

¶ 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;

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.
