פירוש על תענית 45:9

If you were not Choni and a great man.

For ostracism: As we ostracize [somone] on account of the honor of the master. And he cast [irreverent] statements and said, "I did not ask for this."

For were these years like the years of Elijah: [A time of] a decree on the stoppage of the rain.

And the key for rain was in Elijah’s hands: We teach [this version of the text].

Wouldn’t the name of Heaven have been desecrated: By way of a question. As Eliyahu had sworn (I Kings 17:1), "As the Lord lives [...], there will be no dew or rain except by my word"; and you swore that you would not move until rain falls.

Wouldn’t the name of Heaven have been desecrated: As one or the other would come to a vain oath.

Wouldn’t the name of Heaven have been desecrated by you, etc.: See the commentary of Rashi. However the expression, "desecrated by you," would appear to be better explained [as], that you would come to a false oath, since the key to stop the rain is in the hands of Eliyahu.
