Komentaryo sa Genesis 42:23: Rashi, Rashbam, Radak & Or HaChaim

והם לא ידעו כי שמע יוסף AND THEY KNEW NOT THAT JOSEPH שמע UNDERSTOOD their language, and they said this in his presence.

כי שומע יוסף, he understands, [not only hears. Ed.]

כי המליץ, we already explained the function of the interpreter.

כי המליץ בינתם FOR THE INTERPRETER WAS BETWEEN THEM — for when they had spoken to him there was an interpreter between them who knew both the Hebrew and the Egyptian languages. He interpreted their words to Joseph and Joseph’s words to them. Consequently they were under the impression that Joseph did not understand the Hebrew language.

המליץ THE INTERPRETER — This was Manasseh (Genesis Rabbah 91:8).
