Midrasch zu Bereschit 44:14

And Judah and his brothers came to Joseph’s house (Gen. 44:14). Why did they go to Joseph’s house? Did he not leave each day to preside at court? He had said to himself: “I will not disgrace my brothers before the Egyptians.” And they fell before him on the ground…. “Behold, we are my lord’s bondsmen” (ibid., v. 14–16). This fulfilled the verse And behold, the sun and the moon and the eleven stars bowed down to me (ibid. 37:9). Whereupon Joseph said to them: What deed is this that ye have done? Know ye not that such a man as I will indeed divine (ibid. 44:15). And he said to them also: “I will tell you why this youth stole it. He did so in order to divine through it and learn the whereabouts of his brother.” And Judah said: “What shall we say unto my lord? What shall we speak? Or how shall we clear ourselves?” (ibid., v. 16). What shall we say concerning the first pieces of silver (that were placed in their sacks by the steward)? How shall we speak concerning the second pieces of silver? How shall we clear ourselves in the matter of the cup? God hath found out the iniquity of thy servants (ibid.). Do not read the phrase as matza (“found out”) but as motza (“revealed”).

(Gen. 44:14:) WHEN JUDAH AND HIS BROTHERS CAME TO JOSEPH'S HOUSE. What is the meaning of TO JOSEPH'S HOUSE? Did not he not leave < his house > daily to hold court at the seat of judgment?⁵⁵Gk.: bema (“rostrum”). It is simply that on this day he did not leave < home > so as not to shame his brothers before the Egyptians.
