The festival offering at the season of first-fruits was to be offered on one day only; and was the same with that of the new moon and Passover. It nearly though not entirely accords with the sacrificial offering prescribed in Leviticus 23:18 ff.

Day of the first-fruits - Called also the feast of weeks, and the feast of pentecost. See it explained Exodus 23:14 (note), and Leviticus 23:15 (note).

Also in the day of the firstfruits,.... When the firstfruits of the wheat harvest were brought unto the Lord, which was the day of Pentecost, fifty days from the sheaf of the wave offering being brought:

when ye bring a new meat offering unto the Lord; that is, a meat offering made of the new corn, which were two wave loaves of two tenth deals of fine flour, baked with leaven, Leviticus 23:15.

after your weeks be out; the seven weeks from the passover to Pentecost, even seven complete sabbaths or weeks, Leviticus 23:15.

ye shall have an holy convocation, ye shall do no servile work; see Leviticus 23:21.

The same number of sacrifices is appointed for the day of the first-fruits, i.e., for the feast of Weeks or Harvest feast (cf. Leviticus 23:15-22). The festal burnt-offering and sin-offering of this one day was independent of the supplementary burnt-offering and sin-offering of the wave-loaves appointed in Leviticus 23:18, and was to be offered before these and after the daily morning sacrifice.

Also in the day of the firstfruits, when ye bring a new meat offering unto the LORD, after your {g} weeks be out, ye shall have an holy convocation; ye shall do no servile work:

(g) In counting seven weeks from the Passover to Whit Sunday, as in Le 23:15.

28:26 The day of the first fruits - In the feast of pentecost, Acts 2:1. Your weeks - The seven weeks which you are to number from the passover.

26, 27. in the day of the first-fruits . offer the burnt offering-A new sacrifice is here ordered for the celebration of this festival, in addition to the other offering, which was to accompany the first-fruits (Le 23:18).

28:16-31 By the sacrifices enjoined in this chapter, we are reminded of the continued power of the sacrifice of Christ, and of our continual need to depend thereon. No hurrying employments, or perilous situations, or prosperous circumstances, should cause slackness in our religious exercises; but should rather stir us up to greater diligence in seeking help from, or giving thanks to the Lord. And all is to be accompanied with repentance, faith is the Lord Jesus, and love to him, and to produce true holiness in our conduct towards all men; otherwise God will abhor our most solemn services and abundant devotions. And Christ is able to supply the wants of every day, every week, every month, every year, every ordinance, every case.
