At the back of the first room of the tabernacle was a curtain that separated it from the second room, called the Most Holy Place (Exodus 26:31–33). This curtain was a sacred barrier. Only the high priest could go behind it into the Most Holy Place, and only once a year on the Day of Atonement (Hebrews 9:7; see Exodus 30:6, 10; Leviticus 16:2–34; 23:27–32).
