Leviticus 23:1-5

1Then Adonai spoke to Moses saying:

2“Speak to Bnei-Yisrael, and tell them: These are the appointed moadim of Adonai, which you are to proclaim to be holy convocations—My moadim.

3“Work may be done for six days, but the seventh day is a Shabbat of solemn rest, a holy convocation. You are to do no work—it is a Shabbat to Adonai in all your dwellings.

4“These are the appointed feasts of Adonai, holy convocations which you are to proclaim in their appointed season.

5During the first month, on the fourteenth day of the month in the evening, is Adonai’s Passover.
