Leviticus 23:5-8

King James Version

⁵ In the fourteenth day of the first month at even is the Lord's passover.

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 In the first day ye shall have an holy convocation: ye shall do no servile work therein.

⁸ But ye shall offer an offering made by fire unto the Lord seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
