“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 meat offering, and their drink offerings, even an offering made by fire, of sweet savour unto the LORD.”
King James Version (KJV)
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.
