C. F. Keil and Franz Delitzsch on Genesis 45:2-3

Gen 45:2-3

As soon as all the rest were gone, he broke out into such loud weeping, that the Egyptians outside could hear it; and the house of Pharaoh, i.e., the royal family, was told of it (cf. Gen 45:2 and Gen 45:16). He then said to his brethren: “I am Joseph. Is my father still alive?” That his father was still living, he had not only been informed before (Gen 43:27), but had just been told again; but his filial heart impels him to make sure of it once more. “But his brethren could not answer him, for they were terrified before him:” they were so smitten in their consciences, that from astonishment and terror they could not utter a word.
