וַיֹּ֙אמֶר֙ יְה֣וֹשָׁפָ֔ט הַאֵ֨ין פֹּ֥ה נָבִ֛יא לַיהוָ֖ה ע֑וֹד וְנִדְרְשָׁ֖ה מֵאוֹתֽוֹ׃
האָט יהוֹשפֿט געזאָגט: איז דאָ ניטאָ נאָך אַ נבֿיא פֿון גאָט, אַז מיר זאָלן פֿרעגן בײַ אים?
Rashi
Is there no other prophet of Adonoy? I have a tradition that no two prophets prophesy with the same expression, and these are all saying the same expression.3See Maseches Sanhedrin 89a.4Yehoshofot did not accuse them directly of not being God’s prophets out of respect for Achov.—Radak
