Commentary for Menachot 105:4

Gemara: The rabbinic students said to R' Preida: "R' Ezra, the grandson of R' Avtolas, who is a tenth-generation descendant of R' Elazar ben Azaryah, who was a tenth-generation descendant of Ezra the Scribe, is standing at the door." R' Preida said to them: "What is all this? Why do you give his lineage? ... If he is a scholar and of distinguished ancestry fine. But if he is of distinguished ancestry and is not a scholar, [may fire consume him!]" They answered him: "He is a scholar." [R' Preida] said to them: "Let him enter and come before us." When R' Ezra entered [R'Preida] saw that his mind was unsettled. [R' Preida] therefore began saying,[NOTE: Translated in accord with the Izhbitzer's explanation below]: "'I said to God," etc., 'My good is in other than you.'"
