Genesis 44:14

And Judah and his brethren came to Joseph's house; for he was yet there, having waited for their return. Judah is now the leader among the brothers, a position which was later confirmed to him. And they fell before him on the ground, in speechless terror and abject surrender. This showed the spirit which now lived in them, as well as the fact that they had not permitted Benjamin to return alone and that they willingly placed themselves under the direction of Judah.
