Leviticus 23:2

1 And Jehovah speaketh unto Moses, saying,

2 `Speak unto the sons of Israel, and thou hast said unto them, Appointed seasons of Jehovah, which ye proclaim, holy convocations, [are] these: they [are] My appointed seasons:

3 six days is work done, and in the seventh day [is] a sabbath of rest, a holy convocation; ye do no work; it [is] a sabbath to Jehovah in all your dwellings.

4 `These [are] appointed seasons of Jehovah, holy convocations, which ye proclaim in their appointed seasons:

5 in the first month, on the fourteenth of the month, between the evenings, [is] the passover to Jehovah;

6 and on the fifteenth day of this month [is] the feast of unleavened things to Jehovah; seven days unleavened things ye do eat;

7 on the first day ye have a holy convocation, ye do no servile work;
