Verse 13. - And they said, Thy servants are twelve brethren, the sons of one man in the land of Canaan; and, behold, the youngest - literally, the little one (cf. Genesis 9:24) - is this day with our father, and one - literally, the one, i.e. the other one, ὁ δὲ ἕτερος (LXX.) - is not - i.e. is dead (cf. Genesis 5:24; Genesis 37:30) - in which statement have been seen a sufficient proof that Joseph's brethren had not yet truly repented of their cruelty towards him (Keil); an evidence that time had assuaged all their bitter feelings, both of exasperation against Joseph and of remorse for their unbrotherly conduct (Murphy); a suppression of the truth (Words. worth), if not a direct falsehood (Lawson), since they wished it to be understood that their younger brother was dead, while of that they had no evidence beyond their own cunningly-invented lie (Genesis 37:20) and their own probable surmisings. But in point of fact the inference was natural and reasonable that Joseph was no more, since twenty years had elapsed without any tidings of his welfare, and there was no absolute necessity requiring them to explain to the Egyptian governor all the particulars of their early life. Yet the circumstance that their assertion regarding himself was incorrect may have tended to awaken his suspicions concerning Benjamin.

42:7-20 Joseph was hard upon his brethren, not from a spirit of revenge, but to bring them to repentance. Not seeing his brother Benjamin, he suspected that they had made away with him, and he gave them occasion to speak of their father and brother. God, in his providence, sometimes seems harsh with those he loves, and speaks roughly to those for whom yet he has great mercy in store. Joseph settled at last, that one of them should be left, and the rest go home and fetch Benjamin. It was a very encouraging word he said to them, I fear God; as if he had said, You may be assured I will do you no wrong; I dare not, for I know there is one higher than I. With those that fear God, we may expect fair dealing.And they said, thy servants are twelve brethren,.... Or rather, "were twelve", since one afterwards is said not to be:

the sons of one man in the land of Canaan; of Jacob, who dwelt there; this is said with the same view as before, to show the improbability of their being spies:

and, behold, the youngest is this day with our father: meaning Benjamin, whom Joseph was eager to hear of, and no doubt was glad to hear he was alive, and his father also, and that they were both together in the land of Canaan:

and one is not; is not in the land of the living, is dead; for so they thought Joseph was, who is the person intended, as appears from what both Reuben and Judah afterwards say, Genesis 42:22; and yet he was before them, and was the person they were speaking to: this must be very striking and affecting to Joseph, who knew full well they meant himself.
