Numbers 28:16-19

‘Then on the fourteenth day of the first month shall be the LORD’S Passover. On the fifteenth day of this month shall be a feast, unleavened bread shall be eaten for seven days. On the first day shall be a holy convocation; you shall do no laborious work. 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, having them without defect.
