Leviticus 23:6-8

21st Century King James Version

⁶ And on the fifteenth day of the same month is the Feast of Unleavened Bread unto the Lord; seven days ye must eat unleavened bread.

⁷ On the first day ye shall have a holy convocation; ye shall do no servile work therein.

⁸ But ye shall offer an offering made by fire unto the Lord seven days. On the seventh day is a holy convocation; ye shall do no servile work therein.’”
