Numbers 28:16-19

‘The LORD’S Passover shall be on the fourteenth day of the first month. On the fifteenth day of this month there shall be a feast; unleavened bread shall be eaten for seven days. On the first day there shall be a holy assembly; you shall do no laborious work. But you shall present an offering by fire, a burnt offering to the LORD: two bulls and one ram, and seven male lambs one year old, that you have without defect.
