Leviticus 23:2-8

²Speak unto the children of Israel, and say unto them, Concerning the set feasts of Jehovah, which ye shall proclaim as holy convocations — these are my set feasts.

³Six days shall work be done; but on the seventh day is the sabbath of rest, a holy convocation; no manner of work shall ye do: it is the sabbath to Jehovah in all your dwellings.

⁴These are the set feasts of Jehovah, holy convocations, which ye shall proclaim in their seasons:

⁵In the first month, on the fourteenth of the month, between the two evenings, is the passover to Jehovah.

⁶And on the fifteenth day of this month is the feast of unleavened bread to Jehovah; seven days shall ye eat unleavened bread.

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

⁸And ye shall present to Jehovah an offering by fire seven days; on the seventh day is a holy convocation: no manner of servile work shall ye do.
