Numbers 4:13-20
English Standard Version
Chapter 4
13And they shall take away the ashes from the altar and spread a purple cloth over it. 14And they shall put on it all the utensils of the altar, which are used for the service there, the fire pans, the forks, the shovels, and the basins, all the utensils of the altar; and they shall spread on it a covering of goatskin, and shall put in its poles. 15And when Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, as the camp sets out, after that the sons of Kohath shall come to carry these, but 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.
17The Lord spoke to Moses and Aaron, saying,
18"Let not the tribe of the clans of the Kohathites be destroyed from among the Levites,
19but deal thus with them, that they may live and not die when they come near to the most holy things: Aaron and his sons shall go in and appoint them each to his task and to his burden,
20but they shall not go in to look on the holy things even for a moment, lest they die."
