Hebrews 9:3

9:3 And after the second curtain there was a tent called the holy of holies.

Hebrews 9:7-8

9:7 But only the high priest enters once a year into the inner tent, and not without blood that he offers for himself and for the sins of the people committed in ignorance. 9:8 The Holy Spirit is making clear that the way into the holy place had not yet appeared as long as the old tabernacle was standing.
