Берешит 43:3 Комментарий: Rashi, Radak, Or HaChaim & Siftei Chakhamim

העד העד [THE MAN] DID SOLEMNLY PROTEST UNTO US — The Hebrew is an expression signifying warning and it is derived from the root עוד to bear witness, because a warning is, as a rule, given in the presence of witnesses. Other examples are (Jeremiah 11:7) “I earnestly forewarned (העדותי) your fathers”, and (Exodus 19:21) “Go, warn (העד) the people.

העד העיד, when a caution is issued to people in the presence of witnesses, the caution is not called התראה, “warning,” but עדות, “testimony.”

ויאמר אליו יהודה לאמור, Yehudah said to him, saying, etc. The word לאמור here seems to mean that Yehudah made a variety of suggestions to Jacob all of which were in the nature of a reply to Jacob's arguments against sending Benjamin to Egypt. The most important of these was the reference to the Egyptian ruler's warning that the brothers would not be able to see him (and buy grain) unless they had their younger brother with them. The Torah implies that the brothers did not resort to another reply, namely that they would take Benjamin with them regardless of whether Jacob approved or not. The word לאמור then means they waited for Jacob's word, i.e. permission.

“לא תראו מני בלתי אחיכם אתכם means YE SHALL NOT SEE ME IF YOUR BROTHER BE NOT WITH YOU — Onkelos renders it by אלהין כד אחוכון עמכון ,“except when your brother is with you” adding the word כד when, to which there is no corresponding word in the Hebrew text. He gave the explanation of the word (בלתי) correctly, but he was not particular to translate according to the exact expression used in the text.
