Having made it clear that there is only one sacrifice for sin, the writer continues with the picture of the most holy place in the temple, where only the high priest could enter each year with the blood of the sacrifice for sins. He reminds the believers that they now worship God in his presence as if they were standing in the most holy place.
Here this means all believers in Christ, whether male or female. Alternate translation: "brothers and sisters" or "fellow believers" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-gendernotations]])
