Exodus 33:7-9

Now Moses used to take the tent and pitch it outside the camp, a good distance from the camp, and he called it the tent of meeting. And everyone who sought the LORD would go out to the tent of meeting which was outside the camp. And it came about, whenever Moses went out to the tent, that all the people would arise and stand, each at the entrance of his tent, and gaze after Moses until he entered the tent. Whenever Moses entered the tent, the pillar of cloud would descend and stand at the entrance of the tent; and the LORD would speak with Moses.
