Numbers 4:5-6, 12

“When the camp is ready to set out, Aaron and his sons are to go in and take down the covering curtain and cover the Chest of The Testimony with it. Then they are to cover this with a dolphin skin, spread a solid blue cloth on top, and insert the poles.

“They are to take all the articles used in ministering in the Sanctuary, wrap them in a blue cloth, cover them with dolphin skins, and place them on a carrying frame.
