Reuven spitzer asks:
Surely the Maharsha on this Daf knew that Aharon was not the Bechor. So why did he write that Aharon was the bechor?

The Kollel replies:
Dear Reuven,
The Sefer Benayahu of the Ben Ish Chai asks your question on the Maharsha, and doesn't answer. However, the Midrash Rabah, Bamidbar 6:2, says that Aharon was a Bechor! (although the Etz Yosef admits that Miryam was older). Perhaps the oldest boy in the house had rights to performing Avodah.
All the best,
Reuven Weiner
