申命记 9:20

ובאהרן התאנף ה׳ AND WITH AARON THE LORD WAS ANGRY, because he listened to you. להשמידו TO DESTROY HIM — this denotes the extermination of one’s children, and so, too, it states, (Amos 2:9) “And I destroyed (ואשמיד) his fruit (offspring) from above” (Leviticus Rabbah 7:1). .(אחרי מות AND I PRAYED FOR AARON ALSO, and my prayer availed to atone half, so that only two of his sons died, and two remained alive.

וּֽבְאַהֲרֹ֗ן הִתְאַנַּ֧ף יְהֹוָ֛ה מְאֹ֖ד לְהַשְׁמִיד֑וֹ וָֽאֶתְפַּלֵּ֛ל גַּם־בְּעַ֥ד אַהֲרֹ֖ן בָּעֵ֥ת הַהִֽוא׃

And the Lord was very angry with Aharon to have destroyed him: and I prayed for Aharon also at the same time.
