2. Mose 26:33

"Thither (where the curtain hands under the loops) within the curtain shalt thou bring the ark of testimony (Exo 25:16-22), and the curtain shall divide unto you between the holy place and the most holy" (הקּדשׁים קדשׁ the holy of holies). The inner compartment was made into the most holy place through the ark of the covenant with the throne of grace upon it.

Moses here receives instructions, I. Concerning the inner curtains of the tent or tabernacle, and the coupling of those curtains (Exo 26:1-6). II. Concerning the outer curtains which were of goats' hair, to strengthen the former (Exo 26:7-13). III. Concerning the case or cover which was to secure it from the weather (Exo 26:14). IV. Concerning the boards which were to be reared up to support the curtains, with their bars and sockets (v. 15-30). V. The partition between the holy place and the most holy (Exo 26:31-35). VI. The veil for the door (Exo 26:36, Exo 26:37). These particulars, thus largely recorded, seem of little use to us now; yet, having been of great use to Moses and Israel, and God having thought fit to preserve down to us the remembrance of them, we ought not to overlook them. Even the antiquity renders this account venerable.

26:33 The Most Holy Place was the earthly dwelling of the Lord. It contained the Ark of the Covenant, from which the Lord would give his commands for the people of Israel (25:22). The Most Holy Place was approximately 15 feet wide, 15 feet deep, and 15 feet high.
