Jewish Burn Offerings

Can you please give me your comments as to why in Leviticus 23:18 for the burnt offerings one young bullock and two rams are required, but then in Numbers 28:27, in speaking of the same feast, two young bullocks and one ram are required?

Commentators that I consulted made two observations respecting the inquiry. One, the first five books of the Old Testament, or Pentateuch, represent history. Therefore, they respectively represent the details of events at different times. Hence, one would not expect necessarily for exact duplication from one historical event to another, especially if God expressly were directing how He desired to be worshipped at different junctures in history. Two, some commentators suppose that differences in details between Leviticus 23 and Numbers 28 pertain to additional feasts and sacrifices in Numbers to those appearing in Leviticus. Third, I offer that the two texts substantially corroborate each other and counting language differences do not materially disarm that general agreement, especially in a law of God that is no longer in force for people living today.
