Leviticus 23:5-13

⁵In the first month, on the fourteenth day of the month at dusk, is the LORD'S passover.

⁶And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD; seven days ye shall eat unleavened bread.

⁷In the first day ye shall have a holy convocation; ye shall do no manner of servile work.

⁸And ye shall bring an offering made by fire unto the LORD seven days; in the seventh day is a holy convocation; ye shall do no manner of servile work.

⁹And the LORD spoke unto Moses saying:

¹⁰Speak unto the children of Israel, and say unto them: When ye are come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring the sheaf of the first-fruits of your harvest unto the priest.

¹¹And he shall wave the sheaf before the LORD, to be accepted for you; on the morrow after the sabbath the priest shall wave it.

¹²And in the day when ye wave the sheaf, ye shall offer a he-lamb without blemish of the first year for a burnt-offering unto the LORD.

¹³And the meal-offering thereof shall be two tenth parts of an ephah of fine flour mingled with oil, an offering made by fire unto the LORD for a sweet savour; and the drink-offering thereof shall be of wine, the fourth part of a hin.
