Leviticus 23:2-4

King James Version

² Speak unto the children of Israel, and say unto them, Concerning the feasts of the Lord, which ye shall proclaim to be holy convocations, even these are my feasts.

³ Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the Lord in all your dwellings.

⁴ These are the feasts of the Lord, even holy convocations, which ye shall proclaim in their seasons.
