4 “These are the appointed feasts of the Lord, the holy convocations, which you shall proclaim at the time appointed for them. 5 In the first month, on the fourteenth day of the month in the evening,* is the Lord’s passover. 6 And on the fifteenth day of the same month is the feast of unleavened bread to the Lord; seven days you shall eat unleavened bread. 7 On the first day you shall have a holy convocation; you shall do no laborious work. 8 But you shall present an offering by fire to the Lord seven days; on the seventh day is a holy convocation; you shall do no laborious work.”

9 And the Lord said to Moses, 10 “Say to the people of Israel, When you come into the land which I give you and reap its harvest, you shall bring the sheaf of the first fruits of your harvest to the priest; 11 and he shall wave the sheaf before the Lord, that you may find acceptance; on the morrow after the sabbath the priest shall wave it.
