Ye shall bring out of your habitations two wave loaves of two tenth deals: they shall be of fine flour; they shall be baken with leaven; they are the firstfruits unto the LORD.
Ye shall bring out of your habitation ... Since the presentation of these loaves would take place, not in the dark, but certainly in daylight, this may explain the special expression, "the day of Pentecost was fully come" (Acts 2:1-47) - i:e., in the morning of the day, which commenced on the preceding evening. These loaves were made of "fine" or wheaten flour, the quantity contained in them being somewhat more than 10 lbs. weight. Since the wave-sheaf gave the signal for the commencement, the two loaves solemnized the termination of the harvest season. They were the first-fruits of that season, being offered unto the Lord by the priest in name of the whole nation (see the note at Exodus 34:22).
The loaves used at the Passover were unleavened, those presented at Pentecost were leavened-a difference which is thus accounted for-that the one was a memorial of the bread hastily prepared at their departure, while the other was a tribute of gratitude to God for their daily food, which was leavened. 'The feast of Pentecost prefigured the mission of the Holy Spirit-the first-fruits of the Spirit which followed that sacred day on which the law was given, and by which the spirit of bondage was introduced, as it also prefigured the first-fruits of the new Church (Acts 2:1-47), and of the ministry of the apostles, and of that new bread with which the Jews first, and then the Gentiles, were to be fed' (Spanheim, 'Chronol. Sac. Par.,' 1:, cap. 15).
