Leviticus 23:1-6

1 And the LORD spoke to Moses, saying,
2 Speak to the children of Israel, and say to 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, a holy convocation: ye shall do no work [in it]: it [is] the sabbath of the LORD in all your dwellings.
4 These [are] the feasts of the LORD, holy convocations, which ye shall proclaim in their seasons
5 In the fourteenth [day] of the first month at evening [is] the LORD'S passover.
6 And on the fifteenth day of the same month [is] the feast of unleavened bread to the LORD, seven days ye must eat unleavened bread.
