John Chrysostom
It obscured their understanding. "And they tore their clothes, and putting on their garments again they returned to the city."
Which when he had searched, beginning at the eldest, and ending at the youngest, he found the cup in Benjamin's sack.
וַיְחַפֵּ֕שׂ בַּגָּד֣וֹל הֵחֵ֔ל וּבַקָּטֹ֖ן כִּלָּ֑ה וַיִּמָּצֵא֙ הַגָּבִ֔יעַ בְּאַמְתַּ֖חַת בִּנְיָמִֽן׃
3 Church Fathers comment on this verse
It obscured their understanding. "And they tore their clothes, and putting on their garments again they returned to the city."
They quickly opened their garments. The governor commenced the inspection with Reuben's robe, and upon not discovering the cup among the older brothers' robes, he lamented the impossibility of returning to his homeland. Joseph's brothers reassured him, saying, "Examine the younger brother’s robes and do so swiftly, for perhaps the cup belonging to your master will be found in your household." The steward, seemingly acting on their suggestion, reached into the vest, but found no cup and wished to cease the search. However, when Benjamin was called to have his garment examined, he carelessly reached in and pulled out the cup.
In this manner, Christ discovers within us the precious silver that He has graciously provided. We possess this silver through both our inherent nature and the divine grace granted by our Redeemer. While the gifts of Christ may be invisible to our eyes, He actively imparts and cultivates them in a hidden way. His gifts are offered to all, yet only a few manage to preserve them without loss. He does not bestow everything upon everyone; the wheat is shared among many, but the cup of salvation is granted to the one endowed with prophetic and priestly gifts. Indeed, it is only the prophet who can declare, "I will take the cup of salvation, and call upon the name of the Lord" (Psalm 115:4).
The light of divine instruction was already evident in Paul’s being, for he was well-versed in the law (cf. Acts 22:3). However, due to his initial rejection of God’s truth, the cup remained sealed within his bag, the gospel truth obscured by the Law, akin to a candle hidden beneath a container (cf. Rom. 6:20; Matt. 5:15; Mk. 4:21; Lk. 11:33). Yet, Ananias was sent to Paul, blessing him and laying hands on him (cf. Acts 9:12, 17), which unfastened the sack. Once the sack was opened, the silver shone brightly; the scales fell from his eyes as if the bindings of the sack had been removed, and he suddenly gained his sight (cf. Acts 9:18). His bindings represented disbelief, and their release signified faith. Thus, once the sack was unbound—symbolizing the veil of the law that rested upon the hearts of the Jews—Paul turned to the Lord, liberated from his constraints, and embraced the grace of freedom, affirming, "But we all, with open face, beholding as in a glass the glory of the Lord, are changed into the same image" (cf. 2 Corinthians 3:15-18).
