Exodus 33:7, 9

Now Moses used to take the tent and to pitch it without the camp, afar off from the camp; and he called it, The tent of meeting. And it came to pass, that every one that sought Jehovah went out unto the tent of meeting, which was without the camp.

And it came to pass, when Moses entered into the Tent, the pillar of cloud descended, and stood at the door of the Tent: and Jehovah spake with Moses.
