Numbers 28:18

16“‘In the first month, on the fourteenth day of the month, is the LORD’s Passover.

17On the fifteenth day of this month shall be a feast. Unleavened bread shall be eaten for seven days.

18In the first day shall be a holy convocation. You shall do no regular work,

19but you shall offer an offering made by fire, a burnt offering to the LORD: two young bulls, one ram, and seven male lambs a year old. They shall be without defect,

20with their meal offering, fine flour mixed with oil. You shall offer three tenths for a bull, and two tenths for the ram.
