Leviticus 23:15-21

And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave-offering; seven sabbaths shall there be complete: even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meal-offering unto Jehovah. Ye shall bring out of your habitations two wave-loaves of two tenth parts of an ephah: they shall be of fine flour, they shall be baken with leaven, for first-fruits unto Jehovah. And ye shall present with the bread seven lambs without blemish a year old, and one young bullock, and two rams: they shall be a burnt-offering unto Jehovah, with their meal-offering, and their drink-offerings, even an offering made by fire, of a sweet savor unto Jehovah. And ye shall offer one he-goat for a sin-offering, and two he-lambs a year old for a sacrifice of peace-offerings. And the priest shall wave them with the bread of the first-fruits for a wave-offering before Jehovah, with the two lambs: they shall be holy to Jehovah for the priest. And ye shall make proclamation on the selfsame day; there shall be a holy convocation unto you; ye shall do no servile work: it is a statute for ever in all your dwellings throughout your generations.
