וַיִּגַּ֨שׁ אֵלָ֜יו יְהוּדָ֗ה וַיֹּאמֶר֮ בִּ֣י אֲדֹנִי֒ יְדַבֶּר־נָ֨א עַבְדְּךָ֤ דָבָר֙ בְּאָזְנֵ֣י אֲדֹנִ֔י וְאַל־יִ֥חַר אַפְּךָ֖ בְּעַבְדֶּ֑ךָ כִּ֥י כָמ֖וֹךָ כְּפַרְעֹֽה׃
유다가 그에게 가까이 가서 가로되 내 주여 청컨대 종으로 내 주의 귀에 한 말씀을 고하게 하소서 주의 종에게 노하지 마옵소서 주는 바로와 같으심이니이다
Rashi on Genesis
ויגש אליו וגו' . . . דבר באזני אדני THEN JUDAH CAME NEAR TO HIM etc. [LET THY SERVANT SPEAK] A WORD IN MY LORD S EARS etc. May my words penetrate into your ears (Genesis Rabbah 93:6).
Ramban on Genesis
LET THY SERVANT, I PRAY THEE, SPEAK A WORD. The intent thereof is to say that he [Judah] will speak but a few words which will not burden Joseph. In my opinion, the correct interpretation is that “a word” refers to the exchange concerning which he is to plead before him, namely, that Joseph exchange him for his brother Benjamin, for he will not ask any other thing of him, and all of the rest of his words are an appeasement and a plea for this exchange.
Rashbam on Genesis
כי כמוך כפרעה, seeing that Your position is one equivalent to that of king, I am afraid of your anger.
