23:18 One bullock and two rams - In Num 28:11,19, it is two young bullocks and one ram. Either therefore it was left to their liberty to chuse which they would offer, or one of the bullocks there, and one of the rams here, were the peculiar sacrifices of the feast day, and the other were attendants upon the two loaves, which were the proper offering at this time. And the one may be mentioned there, and the other here, to teach us, that the addition of a new sacrifice did not destroy the former, but both were to be offered, as the extraordinary sacrifices of every feast did not hinder the oblation of the daily sacrifice.
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.
