Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

"The priest shall wave them (the two lambs of the peace-offerings), together with the loaves of the first-fruits, as a wave-offering before Jehovah; with the two lambs (the two just mentioned), they (the loaves) shall be holy to Jehovah for the priest." In the case of the peace-offerings of private individuals, the flesh belonged for the most part to the offerer; but here, in the case of a thank-offering presented by the congregation, it was set apart for the priest. The circumstance, that not only was a much more bountiful burnt-offering prescribed than in the offerings of the dedicatory sheaf at the commencement of harvest (Lev 23:12), but a sin-offering and peace-offering also, is to be attributed to the meaning of the festival itself, as a feast of thanksgiving for the rich blessing of God that had just been gathered in. The sin-offering was to excite the feeling and consciousness of sin on the part of the congregation of Israel, that whilst eating their daily leavened bread they might not serve the leaven of their old nature, but seek and implore from the Lord their God the forgiveness and cleansing away of their sin. Through the increased burnt-offering they were to give practical expression to their gratitude for the blessing of harvest, by a strengthened consecration and sanctification of all the members of the whole man to the service of the Lord; whilst through the peace-offering they entered into that fellowship of peace with the Lord to which they were called, and which they were eventually to enjoy through His blessing in their promised inheritance. In this way the whole of the year's harvest was placed under the gracious blessing of the Lord by the sanctification of its commencement and its close; and the enjoyment of their daily food was also sanctified thereby. For the sake of this inward connection, the laws concerning the wave-sheaf and wave-loaves are bound together into one whole; and by this connection, which was established by reckoning the time for the feast of Weeks from the day of the dedication of the sheaf, the two feasts were linked together into an internal unity. The Jews recognised this unity from the very earliest times, and called the feast of Pentecost Azqereth (Greek, Ἀσαρθά), because it was the close of the seven weeks (see at Lev 23:36; Josephus, Ant. iii. 10). (Note: A connection between the feast of Pentecost and the giving of the law, which Maimonides (a.d. † 1205) was the first to discover, is not only foreign to the Mosaic law, but to the whole of the Jewish antiquity; and even Abarbanel expressly denies it.)
