Note the contradiction in the following two verses, discussing the requirement to bring offerings on the Passover Festival:
• Verse Lv23-08 states
  • And ye shall bring an offering made by fire unto HaShem ....
• Verse Nu28-27 states
  • but ye shall bring an offering made by fire, an elevation-offering unto HaShem:
  • • two young bullocks,
    • one ram,
    • seven he-lambs of the first year.

We see the contradiction, indicated by the presence of an extra bullet in the second citation providing a list of animals to be brought. Which is it? Is there an obligation of bringing 2 oxen, 1 ram and 7 lambs, or is the obligation to simply bring [any] offering?

Rashi resolves this contradiction using the broad-literal method:
• You must bring an offering under all circumstances
• If possible it is preferred to bring 2 oxen, 1 ram, and 7 lambs.
In other words
• the 2-oxen verse indicates the preferred obligation.
• The Leviticus verse indicates the if-you-don't have obligation.
So if e.g. you only have 7 lambs and 1 ram but no oxen then you bring the 7 lambs and 1 ram without the oxen.

Advanced Rashi: Rashi literally says as follows: The 7 lambs, 1 ram and 2 oxen are independent requirements. If you don't have all you bring whatever you do have. What I have added to Rashi is the derivation of this exegesis from the contradiction method. Precisely because one verse gives details - bring 2 oxen, 1 ram, 7 lambs - and the other verse gives generality - bring - therefore, I infer that the details are obligatory and the general bring applies when all species are not there.

The astute reader should note the added word, elevation offering in the alignment of the above two verses: bring an offering of fire unto Hashem vs. bring an offering of fire, an elevation offering, unto Hashem. I know of no Rashi or Midrashic analysis explaining this alignment anomaly. Typically, when studying Rashi the use of proper methodology exposes other similar stylistic requirements requiring exegesis.
