The Festival of Weeks

¹⁵ And from the day after the sabbath, from the day on which you bring the sheaf of the elevation offering, you shall count off seven weeks; they shall be complete. ¹⁶ You shall count until the day after the seventh sabbath, fifty days; then you shall present an offering of new grain to the Lord.
