Leviticus 23:3-5

Darby Translation

³ Six 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.

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

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