Leviticus 23:5-11

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

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

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

⁸and ye have brought near a fire-offering to Jehovah seven days; in the seventh day is a holy convocation; ye do no servile work.'

⁹And Jehovah speaketh unto Moses, saying,

¹⁰'Speak unto the sons of Israel, and thou hast said unto them, When ye come in unto the land which I am giving to you, and have reaped its harvest, and have brought in the sheaf, the beginning of your harvest unto the priest,

¹¹then he hath waved the sheaf before Jehovah for your acceptance; on the morrow of the sabbath doth the priest wave it.
