וַיָּבֹ֨א יְהוּדָ֤ה וְאֶחָיו֙ בֵּ֣יתָה יוֹסֵ֔ף וְה֖וּא עוֹדֶ֣נּוּ שָׁ֑ם וַיִּפְּל֥וּ לְפָנָ֖יו אָֽרְצָה׃
I przyszedł Jehuda i bracia jego do domu Josefa, który jeszcze tam był, i padli przed nim na ziemię.
Rashi on Genesis
עודנו שם HE WAS YET THERE — for he was waiting for them.
Rabbeinu Bahya
ויפלו לפניו ארצה, “they fell to the ground before him (Joseph).” All ten brothers fell to the ground plus Binyamin. This was the realisation of Joseph’s dream in which eleven stars bowed down to him (37,9).
Rav Hirsch on Torah
Nun tritt Juda hervor; denn nun gilt es, seine Bürgschaft zu lösen.
