VaEira: Self-Centered Gratitude
They don’t call them “the magic words” for nothing.
Continuing our theme from last week, Rashi (Sh’mos 7:19) writes that Moshe Rabbeinu could not be the one to set off the plagues of Blood and Frogs by striking the Nile, because he owed a debt of gratitude to the river for protecting him as a helpless baby. Similarly, Rashi (ibid. 8:12) comments that Moshe could not summon the Lice by banging his staff on the Egyptian soil out of a sense of hakaras ha’tov to the ground, which had hidden the Egyptian he killed many years earlier. For these reasons, Aharon was chosen to carry out these makos.
