C. F. Keil and Franz Delitzsch on Genesis 43:6-7

Gen 43:6-7

To the father’s reproachful question, why they had dealt so ill with him, as to tell the man that they had a brother, Judah replied: “The man asked after us and our kinsmen: Is your father yet alive? have ye a brother? And we answered him in conformity (פּי על as in Exo 34:27, etc.) with these words (i.e., with his questions). Could we know, then, that he would say, Bring your brother down?” Joseph had not made direct inquiries, indeed, about their father and their brother; but by his accusation that they were spies, he had compelled them to give an exact account of their family relationships. So that Judah, when repeating the main points of the interview, could very justly give them in the form just mentioned.
