holies.22 In Isaiah 6 the Lord is not in the דְּבִיר, or holy of holies, He is in the הֵיכָל, the front room, the great hall of His palace. Note that the standard term for the temple as a whole, בַּיִת, is used in verse 4 and clearly contrasts with הֵיכָל in verse 1. Secondly, Isaiah says that the bases of the doorposts shook. This makes it absolutely clear that the Lord is in the front room, because Isaiah is at the doorway and would not have been able to see into the back room from the doorway.
