When Aaron and his sons have finished covering the holy objects and all their equipment, as soon as the camp is ready to move, the Kohathites shall come and do the carrying. But they must not touch the holy objects, or they will die. These are the transportation duties of the Kohathites regarding the Tent of Meeting.
Jewish Publication Society of America Version (JPS1917) - Numbers 4:15 >And when Aaron and his sons have made an end of covering the holy furniture, and all the holy vessels, as the camp is to set forward — after that, the sons of Kohath shall come to bear them; but they shall not touch the holy things, lest they die. These things are the burden of the sons of Kohath in the tent of meeting.
