Also in the day of the firstfruits, when ye bring a new meat offering unto the LORD, after your weeks be out, ye shall have an holy convocation; ye shall do no servile work:
In the day of the first-fruits ... offer the burnt offering. A new sacrifice is ordered for the celebration of this festival, in addition to the other offering, which was to accompany the first-fruits (Leviticus 23:18). The "feast of weeks" is here called "the day of the first-fruits," because at that time were offered the first of their second or wheat harvest; hence, it is called "the feast of harvest" (Exodus 23:16), and also, in a later age, Pentecost, from its being celebrated 50 days after the Passover.
