Numbers 28:17-19

New Revised Standard Version, Anglicised Catholic Edition

¹⁷ And on the fifteenth day of this month is a festival; for seven days shall unleavened bread be eaten. ¹⁸ On the first day there shall be a holy convocation. You shall not work at your occupations. ¹⁹ You shall offer an offering by fire, a burnt-offering to the Lord: two young bulls, one ram, and seven male lambs a year old; see that they are without blemish.
