Parashat Tzav teaches that one of the core responsibilities of the Kohanim was to remove the ashes of the Olah sacrifice from the altar every morning, terumat hadeshen. Although it was dirty work to clear away the sacrificial remains, it was also holy work which the Kohen performed while wearing priestly clothes. The uniform that the Kohen wears teaches us a tremendous amount about how challenging it can be to take on roles of power and responsibility. We often feel like impostors, unsuited to represent what we are being asked to represent or serve in the way that we need to serve. Seeing how the Kohanim were able to dress for and succeed in their roles of religious leadership can teach us how to overcome our sense that we just aren’t good enough and become the people we can and need to be.
