Dan sera l’arbitre de son peuple, sous lui se grouperont les tribus d’Israël.
Derashot HaRan
In my view, however, this parshah intimates to each tribe what will befall him, just as the episode of Samson was intimated to the tribe of Dan, Jacob alluding to it by saying (Genesis 49:16): "Dan shall judge his people…," our sages commenting (Sotah 9b) that "that bites the horse's heels" (Genesis 49:17) refers to the two pillars upon which the Philistine temple rested, and that when Samson saw that he had fallen into the hands of his foes he called out (Ibid 18): "In Your salvation I hope, O L-rd!" In the same way, what is stated of Judah is stated by way of apprisal and assurance, so that "The staff shall not depart from Judah" is to be taken as meaning that though their kings would sin, their punishment would not be so great as to cause the kingdom to be removed from them and to depart from them entirely.
