Numbers 1:51-52

⁵¹And when the tabernacle setteth forward, the Levites shall take it down; and when the tabernacle is to be pitched, the Levites shall set it up; and the common man that draweth nigh shall be put to death.

⁵²And the children of Israel shall pitch their tents, every man with his own camp, and every man with his own standard, according to their hosts.
