Numbers 29:7-8

7On the tenth day of the seventh month, you must come together for a holy meeting. During that day, you must make yourselves humble. And you must not do any work.

8You must offer a burnt offering to the Lord. The smell of the smoke will make the Lord happy. Offer one young bull, one male sheep and seven male lambs that are one year old. The animals must not have anything wrong with them.
