The writer of Hebrews continues to present Jesus as the superior version of all that Israel had known before. This time, he turns his attention to the high priestly family and the person of Aaron, the original high priest. The revelation from God, here, is that we don't have to enter the Holy of Holies with fear and trepidation any more. Because Jesus, the Great High Priest, is permanently in the Holy of Holies, we can enter with confidence and find grace to help in time of need.
