Leviticus 23:6 ASV

⁴  These are the set feasts of Jehovah, even holy convocations, which ye shall proclaim in their appointed season.

⁵  In the first month, on the fourteenth day of the month at even, is Jehovah's passover.

⁶  And on the fifteenth day of the same month is the feast of unleavened bread unto Jehovah: seven days ye shall eat unleavened bread.

⁷  In the first day ye shall have a holy convocation: ye shall do no servile work.

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