TSK · Numbers 18:5

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

Without the veil of the testimony, in the tent of meeting, shall Aaron keep it in order from evening to morning before Jehovah continually: it shall be a statute for ever throughout 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 tent of meeting, and to make 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 his father's house, the Korahites, were over the work of the service, keepers of the thresholds of the tent: and their fathers had been over the camp of Jehovah, keepers of the entry.

And these are the singers, heads of fathers' [houses] of the Levites, [who dwelt] in the chambers [and were] free [from other service] ; for they were employed in their work day and night.

and that they should keep the charge of the tent of meeting, and the charge of the holy place, and the charge of the sons of Aaron their brethren, for the service of the house of Jehovah.

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, my child Timothy, according to the prophecies which led the way to thee, that by them thou mayest war the good warfare;

I charge [thee] in the sight of God, and Christ Jesus, and the elect angels, that thou observe these things without prejudice, doing nothing by partiality.
