Numbers 4:1-8

1 Then the LORD said to Moses and Aaron,
2 “Record the names of the members of the clans and families of the Kohathite division of the tribe of Levi.
3 List all the men between the ages of thirty and fifty who are eligible to serve in the Tabernacle.
4 “The duties of the Kohathites at the Tabernacle will relate to the most sacred objects.
5 When the camp moves, Aaron and his sons must enter the Tabernacle first to take down the inner curtain and cover the Ark of the Covenant with it.
6 Then they must cover the inner curtain with fine goatskin leather and spread over that a single piece of blue cloth. Finally, they must put the carrying poles of the Ark in place.
7 “Next they must spread a blue cloth over the table where the Bread of the Presence is displayed, and on the cloth they will place the bowls, ladles, jars, pitchers, and the special bread.
8 They must spread a scarlet cloth over all of this, and finally a covering of fine goatskin leather on top of the scarlet cloth. Then they must insert the carrying poles into the table.
