Leviticus 23:15-21

¹⁵You shall count to you from the next day after the Sabbath, from the day that you brought the sheaf of the wave-offering; seven Sabbaths shall there be complete: ¹⁶even to the next day after the seventh Sabbath shall you number fifty days; and you shall offer a new meal-offering to Yahweh. ¹⁷You 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 baked with yeast, for first-fruits to Yahweh. ¹⁸You shall present with the bread seven lambs without blemish a year old, and one young bull, and two rams: they shall be a burnt offering to Yahweh, with their meal-offering, and their drink-offerings, even an offering made by fire, of a sweet savor to Yahweh. ¹⁹You shall offer one male goat for a sin-offering, and two he-lambs a year old for a sacrifice of peace-offerings. ²⁰The priest shall wave them with the bread of the first-fruits for a wave-offering before Yahweh, with the two lambs: they shall be holy to Yahweh for the priest. ²¹You shall make proclamation on the same day; there shall be a holy convocation to you; you shall do no servile work: it is a statute forever in all your dwellings throughout your generations.
