TSK · Numbers 17:7

On the day that the tabernacle was raised up, the cloud covered the tabernacle, even the Tent of the Testimony: and at evening it was over the tabernacle as it were the appearance of fire, until morning.

Your brothers also, the tribe of Levi, the tribe of your father, bring near with you, that they may be joined to you, and minister to you: but you and your sons with you shall be before the tent of the testimony.
