51Whenever the tabernacle is to move, the Levites are to take it down, and whenever it is to be pitched, the Levites are to set it up. Any outsider who goes near it must be put to death.
52The Israelites are to camp by their divisions, each man in his own camp and under his own standard.
53But the Levites are to camp around the tabernacle of the Testimony and watch over it, so that no wrath will fall on the congregation of Israel. So the Levites are responsible for the tabernacle of the Testimony.”
— Numbers 1:51-53
