Offerings at the Feast of Tabernacles
12 On the fifteenth day of the seventh month you will have a holy convocation. You will do no ordinary work, and you will keep a feast to the Lord seven days. 13 And you will offer a burnt offering, a sacrifice made by fire, as a pleasing aroma to the Lord: thirteen young bulls, two rams, and fourteen lambs in their first year, without blemish.
