:
1 And he commanded the steward of his house, saying, Fill the men's sacks with food, as much as they can carry, and put every man's money in his sack's mouth. 2 And put my cup, the silver cup, in the sack's mouth of the youngest, and his corn money. And he did according to the word that Joseph had spoken. 3 As soon as the morning was light, the men were sent away, they and their asses. 4 And when they were gone out of the city, and not yet far off, Joseph said unto his steward, Up, follow after the men; and when thou dost overtake them, say unto them, Wherefore have ye rewarded evil for good? 5 Is not this it in which my lord drinketh, and whereby indeed he divineth? ye have done evil in so doing. 6 And he overtook them, and he spake unto them these same words. 7 And they said unto him, Wherefore saith my lord these words? God forbid that thy servants should do according to this thing: 8 Behold, the money, which we found in our sacks' mouths, we brought again unto thee out of the land of Canaan: how then should we steal out of thy lord's house silver or gold? 9 With whomsoever of thy servants it be found, both let him die, and we also will be my lord's bondmen. 10 And he said, Now also let it be according unto your words; he with whom it is found shall be my servant; and ye shall be blameless. 11 Then they speedily took down every man his sack to the ground, and opened every man his sack. 12 And he searched, and began at the eldest, and left at the youngest: and the cup was found in Benjamin's sack. 13 Then they rent their clothes, and laded every man his ass, and returned to the city. 14 And Judah and his brethren came to Joseph's house; for he was yet there: and they fell before him on the ground. 15 And Joseph said unto them, What deed is this that ye have done? wot ye not that such a man as I can certainly divine? 16 And Judah said, What shall we say unto my lord? what shall we speak? or how shall we clear ourselves? God hath found out the iniquity of thy servants: behold, we are my lord's servants, both we, and he also with whom the cup is found. 17 And he said, God forbid that I should do so: but the man in whose hand the cup is found, he shall be my servant; and as for you, get you up in peace unto your father. 18 Then Judah came near unto him, and said, Oh my lord, let thy servant, I pray thee, speak a word in my lord's ears, and let not thine anger burn against thy servant: for thou art even as Pharaoh. 19 My lord asked his servants, saying, Have ye a father, or a brother? 20 And we said unto my lord, We have a father, an old man, and a child of his old age, a little one; and his brother is dead, and he alone is left of his mother, and his father loveth him. 21 And thou saidst unto thy servants, Bring him down unto me, that I may set mine eyes upon him. 22 And we said unto my lord, The lad cannot leave his father: for if he should leave his father, his father would die. 23 And thou saidst unto thy servants, Except your youngest brother come down with you, ye shall see my face no more. 24 And it came to pass when we came up unto thy servant my father, we told him the words of my lord. 25 And our father said, Go again, and buy us a little food. 26 And we said, We cannot go down: if our youngest brother be with us, then will we go down: for we may not see the man's face, except our youngest brother be with us. 27 And thy servant my father said unto us, Ye know that my wife bare me two sons: 28 And the one went out from me, and I said, Surely he is torn in pieces; and I saw him not since: 29 And if ye take this also from me, and mischief befall him, ye shall bring down my gray hairs with sorrow to the grave. 30 Now therefore when I come to thy servant my father, and the lad be not with us; seeing that his life is bound up in the lad's life; 31 It shall come to pass, when he seeth that the lad is not with us, that he will die: and thy servants shall bring down the gray hairs of thy servant our father with sorrow to the grave. 32 For thy servant became surety for the lad unto my father, saying, If I bring him not unto thee, then I shall bear the blame to my father for ever. 33 Now therefore, I pray thee, let thy servant abide instead of the lad a bondman to my lord; and let the lad go up with his brethren. 34 For how shall I go up to my father, and the lad be not with me? lest peradventure I see the evil that shall come on my father.

And the silver cup is put in his sack alone. Benjamin did not know this. So Paul was in error, but he was called. They sent after him in the morning; indeed, the night of his blindness had advanced, and the day of faith was near at hand.

[AD 420] Jerome on Genesis 44:2
(Chapter XLIV - Verse 2) And put the silver of each one in the mouth of the bag, and put my silver cup in the mouth of the youngest one's bag. For bag, it has a peronem or follem in Hebrew. For cup, which we also read in Isaiah (LI, 17), Aquila translated as scyphum, Symmachus as phialam.

[AD 373] Ephrem the Syrian on Genesis 44:12
The brothers did not know what to say; they found it impossible not to put the blame on Benjamin because the cup had come out from his sack, but the money that had twice come out from their own sacks did not permit them to put the blame on him. Then the brothers, confounded by the things that had befallen them, rent their garments and went back weeping to that house from which they had just departed rejoicing.

[AD 397] Ambrose of Milan on Genesis 44:12
The sacks of the brothers are first examined according to the order of age of each brother. God’s Scripture is teaching you a moral lesson. Previously they sat at the banquet in Joseph’s presence in order of age from the firstborn. You see that the place of honor is to be given to the eldest. On the other hand, the sacks of each are searched in order of age7 so that you may know that Paul has been chosen by the judgment of heaven. The rest were examined, but this man was given the preference. The silver cup was not found in the sack of anyone else, only in his sack. What is the meaning of its being put in his humble sack? Joseph … sent the cup so that he might by a holy trick recall the brother whom he loved; yet the light of God’s mysterious plans is clearly reflected.

[AD 397] Ambrose of Milan on Genesis 44:12
Christ finds this money in us which he has himself given us. We possess the money of nature; we also possess the money of grace. Nature is the work of the Creator, grace the gift of the Redeemer. Even though we are unable to see Christ’s gifts, nevertheless he is giving them. He is working in a hidden way and is giving them to all people, but there are few who are able to keep them and not lose them. Yet he does not give all things to all people. Wheat is given to many, but the cup to one, who is presented with the prophetic and priestly function. For it is not everyone but only the prophet who says, “The cup of salvation I will take up, and I will call upon the name of the Lord.” Therefore the word of heavenly teaching already shone in Paul’s body, since he was instructed in the law. But because he was still not subject to the justice of God, the cup was within the sack, the teaching within the law, the lamp within the bushel. Nevertheless Ananias was sent to give a blessing and to lay on his hand and open the sack. When the sack was opened, the money shone forth, and when the scales fell, in a way like fastenings on the sack, Paul saw straightway. His fetter was unbelief; the loosening of it became faith. And for that reason, when the veil that is set over the heart of the Jews was set aside—like the opening of the sack—he turned to the Lord. Free of the bond, he obtained the grace of liberty and said, “But we all, beholding the glory of God with faces unveiled, are transformed into the same image.”

[AD 373] Ephrem the Syrian on Genesis 44:16
Then Judah said, “Before God the sins of your servants have been discovered”—not this one [of the cup] but the one for which we have been requited with these things. “Therefore not only he in whose sack the cup was found but we also will become slaves to our master.” And Joseph said, “Far be it from” the just Egyptian “to do this!” These men, because of their great virtue, do not even eat bread with Hebrews lest they become unclean by them. How then can we do what is foreign to our conduct? The justice that hinders us from sinning against one who has not sinned against us compels us to be avenged on that one who has caused us offence. “The one in whose hand the cup was found shall remain and be a slave.” This will be better for him than freedom, for this later servitude, which will free him from theft, will be better for him than that first freedom that enslaved him to theft.
