5In the fourteenth day of the first month at even 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 must eat unleavened bread.10Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest:12And ye shall offer that day when ye wave the sheaf an he lamb without blemish of the first year for a burnt offering unto the LORD.

12As for the oblation of the firstfruits, ye shall offer them unto the LORD: but they shall not be burnt on the altar for a sweet savour.
