Genesis 46:28

He sent Judah before him. The list of the house of Jacob is followed by an account of the arrival in Egypt. Judah, having shown remarkable qualities of leadership on their previous trip to Egypt, was naturally selected to represent the aged patriarch and announce his arrival. He would also obtain from Joseph necessary instructions as to the place of their settlement, and then return to guide the caravan to Goshen (see on ch. 45:10). The fact that Judah performed this task suggests that he had already been selected by Jacob as inheritor of the birthright. Benjamin, though beloved, was young and lacking in experience, and, as later circumstances proved, he lacked qualities of leadership. Benjamin was only a “wolf,” but Judah was a “lion” (ch. 49:9, 27).
