Restrictions
There was a set of rules to be followed for the Tabernacle, very strict, set on the Old Testament. For example: "For the LORD had said to Moses, 'Exempt the tribe of Levi from the census; do not include them when you count the rest of the Israelites. You must put the Levites in charge of the Tabernacle of the Covenant, along with its furnishings and equipment. They must carry the Tabernacle and its equipment as you travel, and they must care for it and camp around it. Whenever the Tabernacle is moved, the Levites will take it down and set it up again. Anyone else who goes too near the Tabernacle will be executed.'" (Numbers 1:48-51 NLT),
