Leviticus 23:6-8

Amplified Bible

⁶ The Feast of Unleavened Bread to the Lord is on the fifteenth day of the same month; for seven days you shall eat unleavened bread.^{(A) 7} On the first day you shall have a holy convocation (calling together); you shall not do any laborious work [on that day]. ⁸ But you shall present an offering by fire to the Lord for seven days; on the seventh day there shall be a holy convocation; you shall not do any laborious work [on that day].’”
