Matthew Poole and continuators on Leviticus 23:18

18 And ye shall offer with the bread seven lambs without blemish of the first year, and one young bullock, and two rams : they shall be for a burnt-offering unto the LORD, with their meatoffering, and their drink-offerings, even an offering made by fire of sweet savour unto the LORD.

In N[illegible: 1+ letters]b. 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 principal and most 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.
