Hebrews 5:3

Moses then said to Aaron, “Come near to the altar and offer your sin offering and your burnt offering, that you may make atonement for yourself and for the people; then offer the offering for the people, that you may make atonement for them, just as Yahweh has commanded.”

“Then Aaron shall bring near the bull for the sin offering which is for himself, that he may make atonement for himself and for his household.

For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures,

who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself.

but into the second, only the high priest enters once a year, not without taking blood, which he offers for himself and for the sins of the people committed in ignorance.
