14 When Judah and his brothers came to Joseph’s house, he was still there, and they fell to the ground before him. 15 Joseph said to them, “What is this deed that you have done? Do you not know that such a man as I can indeed practice divination?” 16 So Judah said, “What can we say to my lord? What can we speak? And how can we justify ourselves? God has found out the iniquity of your servants; behold, we are my lord’s slaves, both we and the one in whose possession the cup has been found.” 17 But he said, “Far be it from me to do this. The man in whose possession the cup has been found, he shall be my slave; but as for you, go up in peace to your father.”
18 Then Judah approached him, and said, “Oh my lord, may your servant please speak a word in my lord’s ears, and do not be angry with your servant; for you are equal to Pharaoh. 19 “My lord asked his servants, saying, `Have you a father or a brother?’ 20 “We said to my lord, `We have an old father and a little child of his old age. Now his brother is dead, so he alone is left of his mother, and his father loves him.’ 21 “Then you said to your servants, `Bring him down to me that I may set my eyes on him.’ 22 “But we said to my lord, `The lad cannot leave his father, for if he should leave his father, his father would die.’ 23 “You said to your servants, however, `Unless your youngest brother comes down with you, you will not see my face again.’ 24 “Thus it came about when we went up to your servant my father, we told him the words of my lord. 25 “Our father said, `Go back, buy us a little food.’ 26 “But we said, `We cannot go down. If our youngest brother is with us, then we will go down; for we cannot see the man’s face unless our youngest brother is with us.’ 27 “Your servant my father said to us, `You know that my wife bore me two sons; 28 and the one went out from me, and I said, “Surely he is torn in pieces,” and I have not seen him since. 29 `If you take this one also from me, and harm befalls him, you will bring my gray hair down to Sheol in sorrow.’ 30 “Now, therefore, when I come to your servant my father, and the lad is not with us, since his life is bound up in the lad’s life, 31 when he sees that the lad is not with us, he will die. Thus your servants will bring the gray hair of your servant our father down to Sheol in sorrow. 32 “For your servant became surety for the lad to my father, saying, `If I do not bring him back to you, then let me bear the blame before my father forever.’ 33 “Now, therefore, please let your servant remain instead of the lad a slave to my lord, and let the lad go up with his brothers. 34 “For how shall I go up to my father if the lad is not with me–for fear that I see the evil that would overtake my father?”
When they had sold Joseph into slavery, and saw their father’s reaction, it changed their lives forever. They would have taken it all back if they could. But Joseph had never seen that, and so he tested them. Finally, he gets the reaction he was hoping for. To see that his brothers had changed and be glad, maybe overjoyed, to see him again, was what he desired. Judah and his brothers realized by the reaction of their father when Joseph was sold what was most important. It was family that mattered most. With all the things they hated Joseph for, their bond of family should have been more important than that.
