Whenever 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.
Jewish Publication Society of America Version (JPS1917) - Numbers 1:51 >And 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.
