John Chrysostom
They were amazed by this and marveled at how he was aware of the disparity in their ages.
They sat before him, the firstborn according to his birthright, and the youngest according to his age. And they wondered very much;
וַיֵּשְׁב֣וּ לְפָנָ֔יו הַבְּכֹר֙ כִּבְכֹ֣רָת֔וֹ וְהַצָּעִ֖יר כִּצְעִרָת֑וֹ וַיִּתְמְה֥וּ הָאֲנָשִׁ֖ים אִ֥ישׁ אֶל־רֵעֵֽהוּ׃
2 Church Fathers comment on this verse
They were amazed by this and marveled at how he was aware of the disparity in their ages.
Joseph, as if divining from a bowl, arranged his brothers in order of their birthright: the eldest occupied the most esteemed position, while the youngest took the least. It is curious that his brothers did not recognize him when he provided for their needs during their journey, when he returned the silver they had handed over for their initial purchase of food (Gen. 42:25), when he imprisoned Simeon (Gen. 42:24), and when he commanded them to bring Benjamin (Gen. 42:20). They failed to see him when he inquired about their betrayal concerning Benjamin (Gen. 42:20), when he sought to know about Benjamin's welfare (Gen. 42:20), and when he invited them to present him to the court (Gen. 42:20). They also didn't recognize him when he asked after their elderly father (Gen.
43:27), when he looked upon them with disdain (Gen. 42:9), when he welcomed them into his home (Gen. 43:16-17), and when he blessed Benjamin (Gen. 43:29). Ultimately, they were astonished to learn he knew each of their names. Though Joseph masked his identity and his exalted status misled them, they might have recalled his dreams (Genesis 37:7-10). Thus, if they could not see him due to his prominence, his dignity, his eloquence, and his stern approach, it was all by divine will that God concealed Joseph from them until his dreams were realized through those who had conspired to thwart them.
Consider, dear brethren, how Joseph instilled fear among them. He instructed each brother to recline, addressing them by name and in the order of their birth, while pretending to discern their identity through a silver vessel in his hand. Upon setting this bowl down, he tapped it with his right finger, producing a resounding echo that filled the house. After the first strike, he called out, “Let Reuben recline in the place of honor first.” Striking again, he announced, “Simeon, let him take his place next.” With a third strike, he declared, “Let Levi take his seat of honor.” He arranged them all at the table, calling their names in sequence, which caused them to be filled with dread and alarm, leading them to conclude, “He knows each of us.” Their fear intensified regarding the cup, as they pondered among themselves, “Could he know through it that we previously deceived him, claiming that an evil beast had slain Joseph?” Consequently, they were greatly troubled. What was Joseph's intention in this act toward his brothers, revealing the names of each one through the cup? It was to deepen their sense of guilt.
