Leviticus 16:15; Leviticus 16:34; Hebrews 10:3; Exodus 30:10

15 rThen he shall kill the goat of the sin offering that is for the people and bring its blood sinside the veil and do with its blood as he did with the blood of the bull, sprinkling it over the mercy seat and in front of the mercy seat.

34 And this shall be a statute forever for you, that atonement may be made for the people of Israel tonce in the year because of all their sins. And Aaron1 did as the Lord commanded Moses.

But yin these sacrifices zthere is a reminder of sins every year.

10 sAaron shall make atonement on its horns once a year. With the blood of the tsin offering of atonement he shall make atonement for it once in the year throughout your generations. It is most holy to the Lord.
