24 Matanos For the Kohein
Rashi in Korach (18:8) says that after Korach complained about the validity of the Kohanim, Hashem gave them 24 Matnos Kehuna to show that he stands behind them.  The Sifsei Chachomim brings down the full list diving it into three groups.  10 in the Bais HaMikdash, 4 in Yerushalayim, and 10 outside of Yerushalayim.  For a full list of the 24 matanos click here to see Revach Lists.
