Numbers 28:15-19

And one male goat as a sin offering to the Lord; it shall be offered with its drink offering in addition to the continual burnt offering.

‘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.
