Numbers 4:1-25 NIV
The LORD said to Moses and Aaron: “Take a census of the Kohathite branch of the Levites by their clans and families. Count all the men from thirty to fifty years of age who come to serve in the work at the tent of meeting.
“This is the work of the Kohathites at the tent of meeting: the care of the most holy things. When the camp is to move, Aaron and his sons are to go in and take down the shielding curtain and put it over the ark of the covenant law. Then they are to cover the curtain with a durable leather, spread a cloth of solid blue over that and put the poles in place.
“Over the table of the Presence they are to spread a blue cloth and put on it the plates, dishes and bowls, and the jars for drink offerings; the bread that is continually there is to remain on it. They are to spread a scarlet cloth over them, cover that with the durable leather and put the poles in place.
“They are to take a blue cloth and cover the lampstand that is for light, together with its lamps, its wick trimmers and trays, and all its jars for the olive oil used to supply it. Then they are to wrap it and all its accessories in a covering of the durable leather and put it on a carrying frame.
“Over the gold altar they are to spread a blue cloth and cover that with the durable leather and put the poles in place.
“They are to take all the articles used for ministering in the sanctuary, wrap them in a blue cloth, cover that with the durable leather and put them on a carrying frame.
“They are to remove the ashes from the bronze altar and spread a purple cloth over it. Then 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.
“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.
“Eleazar son of Aaron, the priest, is to have charge of the oil for the light, the fragrant incense, the regular grain offering and the anointing oil. He is to be in charge of the entire tabernacle and everything in it, including its holy furnishings and articles.”
The LORD said to Moses and Aaron, “See that the Kohathite tribal clans are not destroyed from among the Levites. So that they may live and not die when they come near the most holy things, do this for them: Aaron and his sons are to go into the sanctuary and assign to each man his work and what he is to carry. But the Kohathites must not go in to look at the holy things, even for a moment, or they will die.”
The LORD said to Moses, “Take a census also of the Gershonites by their families and clans. Count all the men from thirty to fifty years of age who come to serve in the work at the tent of meeting.
“This is the service of the Gershonite clans in their carrying and their other work: They are to carry the curtains of the tabernacle, that is, the tent of meeting, its covering and its outer covering of durable leather, the curtains for the entrance to the tent of meeting
