Numbers 29:12-13

Thomson(i) 12 And on the fifteenth day of this seventh month, there shall be a solemn festival set apart for you. You shall do no sacrificial work. And you shall celebrate this festival to the Lord seven days. 13 And you shall bring, for whole burnt offerings; for an offering of homage; for a smell of fragrance to the Lord, on the first day, thirteen young bulls from the herd, two rams, fourteen lambs of the first year, [they shall be without blemish]
