Numbers 4:15–20
15 And when Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, as the camp sets out, after that mthe sons of Kohath shall come to carry these, nbut they must not touch the holy things, lest they die. These are the things of the tent of meeting that the sons of Kohath are to carry.
16 “And Eleazar the son of Aaron the priest shall have charge of othe oil for the light, the pfragrant incense, qthe regular grain offering, and rthe anointing oil, with the oversight of the whole tabernacle and all that is in it, of the sanctuary and its vessels.”
17 The Lord spoke to Moses and Aaron, saying, 18 “Let not the tribe of the clans of the Kohathites be destroyed from among the Levites, 19 but deal thus with them, that they may live and not die when they come near to sthe most holy things: Aaron and his sons shall go in and appoint them each to his task and to his burden, 20 tbut they shall not go in to look on the holy things even for a moment, lest they die.”
