Numbers 4:14-15

14Then they are to place on it all the utensils used for ministering at the altar, including the firepans, meat forks, shovels and sprinkling bowls. Over it they are to spread a covering of the durable leather and put the poles in place. 15“After Aaron and his sons have finished covering the holy furnishings and all the holy articles, and when the camp is ready to move, only then are the Kohathites to come and do the carrying. But they must not touch the holy things or they will die. The Kohathites are to carry those things that are in the tent of meeting.
