Numbers 4:15–20

¹⁵‘And Aaron hath finished—his sons also—covering the sanctuary, and all the vessels of the sanctuary, in the journeying of the camp, and afterwards do the sons of Kohath come in to bear it, and they do not come unto the holy thing, that they have died; these things are the burden of the sons of Kohath in the tent of meeting.

¹⁶‘And the oversight of Eleazar, son of Aaron the priest, is the oil of the lamp, and the spice-perfume, and the present of continuity, and the anointing oil, the oversight of all the tabernacle, and of all that is in it, in the sanctuary, and in its vessels.’ ¹⁷And Jehovah speaketh unto Moses and unto Aaron, saying, ¹⁸‘Ye do not cut off the tribe of the families of the Kohathite from the midst of the Levites; ¹⁹but this do to them, and they have lived, and do not die in their drawing nigh the holy of holies:—Aaron and his sons go in, and have set them, each man to his service, and unto his burden, ²⁰and they go not in to see when the holy thing is swallowed, that they have died.’
