Leviticus 23:6-8

New King James Version

⁶ And on the fifteenth day of the same month is the Feast of Unleavened Bread to the Lord; seven days you must eat unleavened bread. ^7 (A)On the first day you shall have a holy convocation; you shall do no ^[a]customary work on it. ⁸ But you shall offer an offering made by fire to the Lord for seven days. The seventh day shall be a holy convocation; you shall do no customary work on it.’ ”
