Holy of Holies

The Holy of Holies was the innermost chamber in the wilderness tabernacle, a room so sacred only one person could enter it, and then only one day out of the entire year (Ref: Tabernacle and Ark).

This room was a perfect cube, 15 feet in each direction. Only one object was housed there: the ark of the covenant (Ark of the Testimony). There was no light inside the chamber other than the glow from God’s glory.

A thick, embroidered veil separated the holy place from the Holy of Holies inside the tent of meeting. Embroidered on that curtain were images of cherubim or angels.

The ark was a wooden box overlaid with gold, with statues of two cherubim on top facing each other, their wings touching. The lid, or mercy seat, was where God met with his people.

Inside the ark were the tablets of the Ten Commandments, a pot of manna, Aaron’s almond wood staff, and the Law of Moses [the civil law written by Moses — Not the Ten Commandments written by God on stone tablets] Deuteronomy 31:24-26, 2 Kings 22:8).
 

Regular priests were allowed in the outer holy place, but the Holy of Holies could only be entered by the high priest on the annual Day of Atonement, or Yom Kippur.
