Numbers 28:22-24

22You must also offer a male goat as a sin offering to purify yourselves and make yourselves right with the Lord.

23Present these offerings in addition to your regular morning burnt offering.

24On each of the seven days of the festival, this is how you must prepare the food offering that is presented as a special gift, a pleasing aroma to the Lord. These will be offered in addition to the regular burnt offerings and liquid offerings.
