Leviticus 23:15-21

“Count seven full weeks from the morning after the Sabbath when you brought the sheaf as a Wave-Offering, fifty days until the morning of the seventh Sabbath. Then present a new Grain-Offering to GOD. Bring from wherever you are living two loaves of bread made from four quarts of fine flour and baked with yeast as a Wave-Offering of the first ripe grain to GOD. In addition to the bread, offer seven yearling male lambs without defect, plus one bull and two rams. They will be a Whole-Burnt-Offering to GOD together with their Grain-Offerings and Drink-Offerings—offered as Fire-Gifts, a pleasing fragrance to GOD. Offer one male goat for an Absolution-Offering and two yearling lambs for a Peace-Offering. The priest will wave the two lambs before GOD as a Wave-Offering, together with the bread of the first ripe grain. They are sacred offerings to GOD for the priest. Proclaim the day as a sacred assembly. Don’t do any ordinary work. It is a perpetual decree wherever you live down through your generations.
