Leviticus 23:5-11

5“The fourteenth day of the first month, in the evening, is the Lord’s Passover.

6The fifteenth day of this same month is the Lord’s Festival of Unleavened Bread. For seven days you must eat unleavened bread.

7On the first day there will be a holy assembly. Don’t do any regular work.

8Bring the Lord a sacrifice by fire for seven days. On the seventh day there will be a holy assembly. Don’t do any regular work.”

9The Lord spoke to Moses,

10“Tell the Israelites: When you come to the land I am going to give you and you harvest grain, bring the priest a bundle of the first grain you harvest.

11He will present it to the Lord so that you will be accepted. He will present it on the day after Passover.
