I'm a little confused about the chronology of the Biblical giants Caleb and Pinchas. Caleb appears to have been part of the Exodus generation, and with Joshua, their defense of the Land of Israel merited them to be exempted from the ban upon all other members of that generation from entering into the Land (Numbers 14:38). I read the fascinating discussion about whether the Pinchus in the Book of Numbers is the same as in the Book of Judges (in response to this question), but I'm not clear on whether Pinchas merited entering the Land with Joshua and Caleb because of his zealousness (described in Numbers 25:7-9) or because he was born after the Exodus. Are there sources that explain this?
Exodus 6:25 seems to speak of the birth of Pinchas before the Exodus.
In terms of entering the land of Israel, the Ohr haChaim writes that the decree of death extended from people who were age 20-60, not the ones younger and not the ones older. So Pinchas may have been a young lad at the time of the spies, and the decree would not have extended to him.
