Kodesh ha'Kodashim ≠ DBR ?
From the Jewish Encyclopedia;
The Debir: the oracle or Most Holy Place (1 Kings 6:19; 8:6), called also the "inner house" (6:27), and the "Holy of Holies" (Heb. 9:3). It was 20 cubits in length, breadth, and height. The usual explanation for the discrepancy between its height and the 30-cubit height of the temple is that its floor was elevated, like the cella of other ancient temples<ref>De Vaux, 1961</ref>. It was floored and wainscotted with cedar (1 Kings 6:16), and its walls and floor were overlaid with gold (6:20, 21, 30). It contained two cherubim of olive-wood, each 10 cubits high (1 Kings 6:16, 20, 21, 23-28) and each having outspread wings 10 cubits from tip to tip, so that, since they stood side by side, the wings touched the wall on either side and met in the center of the room. There was a two-leaved door between it and the holy place overlaid with gold (2 Chr. 4:22); also a veil of blue purple and crimson and fine linen (2 Chr. 3:14; compare Exodus 26:33). It had no windows (1 Kings 8:12). It was considered the dwelling-place of God.
