Many days. — Jacob mourned for Joseph not merely during the usual period, but so long as to move even the hearts of those who had wronged him. For not only his daughters, but “all his sons rose up to comfort him.” Probably he had several daughters by Leah and the two handmaidens, Dinah alone having been mentioned by name, because two of her brothers forfeited the birthright by the cruelty with which they avenged her wrong. We learn how long and intense Jacob’s sorrow was from Genesis 45:26-28. His daughters are mentioned also in Genesis 46:7.
