Leviticus 23:3-5

Amplified Bible, Classic Edition

³ Six days shall work be done, but the seventh day is the Sabbath of rest, a holy convocation or assembly by summons. You shall do no work on that day; it is the Sabbath of the Lord in all your dwellings.

⁴ These are the set feasts or appointed seasons of the Lord, holy convocations you shall proclaim at their stated times:

⁵ On the fourteenth day of the first month at twilight is the Lord’s Passover.
