Musar su Genesi 43:33

Let us get back to the brothers who had originally suspected Joseph of harboring personal motives in his quest to become Royalty. Their suspicion is alluded to in פרשת ויגש, and expressed in Psalms 48,5: כי הנה המלכים נועדו עברו יחדו, המה ראו כן תמהו נבהלו נחפזו, רעדה אחזתם שם חיל כיולדה. The part about "See the kings," refers to Joseph and Yehudah; עברה יחדו describes their hatred of each other (from the word evrah for anger); המה ראו כן תמהו is an allusion to Genesis 43, 33 where the brothers ויתמהו, express their amazement to one another at the seating arrangements made by Joseph which placed them in the order of age. The reference to the brothers' terror and fright, נבהלו, etc., is to the moment when Joseph revealed himself and the brothers were frightened (45,3). The words רעדה אחזתם, "Panic seized them", refers to the other brothers who said: "kings are arguing with one another" (the debate between Joseph and Yehudah), "let the kings fight it out among themselves."
