Exodus 40:33 WEB

³¹  Moses, Aaron, and his sons washed their hands and their feet there.

³²  When they went into the tent of meeting, and when they came near to the altar, they washed, as Yahweh commanded Moses.

³³  He raised up the court around the tent and the altar, and set up the screen of the gate of the court. So Moses finished the work.

³⁴  Then the cloud covered the tent of meeting, and the glory of Yahweh filled the tent.

³⁵  Moses wasn't able to enter into the tent of meeting, because the cloud stayed on it, and Yahweh's glory filled the tent.
