The Lord appeared in the tent in a pillar of cloud that ¹  stood above the door of the tent.

the one who was constantly going before you to find places for you to set up camp. He appeared by fire at night and cloud by day, to show you the way you ought to go.

You approached and stood at the foot of the mountain, a mountain ablaze to the sky above it ¹  and yet dark with a thick cloud. ² 

The Lord said these things to your entire assembly at the mountain from the middle of the fire, the cloud, and the darkness with a loud voice, and that was all he said. ¹  Then he inscribed the words ²  on two stone tablets and gave them to me.
