23:15-22 The feast of Weeks was held in remembrance of the giving of the law, fifty days after the departure from Egypt; and looked forward to the outpouring of the Holy Ghost, fifty days after Christ our Passover was sacrificed for us. On that day the apostles presented the first-fruits of the Christian church to God. To the institution of the feast of Pentecost, is added a repetition of that law, by which they were required to leave the gleanings of their fields. Those who are truly sensible of the mercy they received from God, will show mercy to the poor without grudging.
17. Ye shall bring out of your habitations two wave loaves of two tenth deals, &c.—These loaves were made of "fine" or wheaten flour, the quantity contained in them being somewhat more than ten pounds in weight. As 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 Ex 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.
