TSK · Hebrews 5:3

For the Priest“‘If the high priest sins so that the people are guilty, on account of the sin he has committed he must present a flawless young bull to the LORD for a sin offering.

Moses then said to Aaron,“Approach the altar and make your sin offering and your burnt offering, and make atonement on behalf of yourself and on behalf of the people; and also make the people’s offering and make atonement on behalf of them just as the LORD has commanded.”

“He must then slaughter the sin offering goat which is for the people. He is to bring its blood inside the curtain, and he is to do with its blood just as he did to the blood of the bull: He is to sprinkle it on the atonement lid and in front of the atonement lid.

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.
