Leviticus 23:4-14

⁴ These are the set feasts of Jehovah, holy convocations, which ye shall proclaim in their seasons: ⁵ In the first month, on the fourteenth of the month, between the two evenings, is the passover to Jehovah. ⁶ And on the fifteenth day of this month is the feast of unleavened bread to Jehovah; seven days shall ye eat unleavened bread. ⁷ On the first day ye shall have a holy convocation: no manner of servile work shall ye do. ⁸ And ye shall present to Jehovah an offering by fire seven days; on the seventh day is a holy convocation: no manner of servile work shall ye do. ⁹ And Jehovah spoke to Moses, saying, ¹⁰ Speak unto the children of Israel and say unto them, When ye come into the land that I give unto you, and ye reap the harvest thereof, then ye shall bring a sheaf of the first-fruits of your harvest unto the priest. ¹¹ And he shall wave the sheaf before Jehovah, to be accepted for you; on the next day after the sabbath the priest shall wave it. ¹² And ye shall offer that day when ye wave the sheaf, a he-lamb without blemish, a yearling, for a burnt-offering to Jehovah; ¹³ and the oblation thereof: two tenths of fine flour mingled with oil, an offering by fire to Jehovah for a sweet odour; and the drink-offering thereof, of wine, a fourth part of a hin. ¹⁴ And ye shall not eat bread, or roast corn, or green ears, until the same day that ye have brought the offering of your God: [it is] an everlasting statute throughout your generations in all your dwellings.
