Exodus 33:9

And it came to pass, as Moses entered into the tabernacle, the cloudy pillar descended, and stood at the door of the tabernacle, and the Lord talked with Moses.

It happened, when Moses entered into the Tent, that the pillar of cloud descended, stood at the door of the Tent, and spoke with Moses.

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.

And it hath come to pass, at the going in of Moses to the tent, the pillar of the cloud cometh down, and hath stood at the opening of the tent, and He hath spoken with Moses;

As Moses entered the tent, the pillar of cloud would come down and remain at the entrance, and the LORD would speak with Moses.
