Genesis 50:22 - Coke's Commentary on the Holy Bible

Joseph lived an hundred and ten years— A shorter life than his ancestors; because he was the son, says Bishop Patrick, of his father's old age, and lived a great part of his time amidst afflictions and care, having the weight of a great kingdom's affairs lying upon him; for eighty of these years he spent in AEgypt, being but thirty years old when he first stood before Pharaoh. Shuckford says that he governed AEgypt during the reigns of four kings, and died in the twentieth year of the reign of Ramesse-Tubeate, fifty two years after his father, and in the year of the world 2367. He had the pleasure of seeing his father's prophetic blessing upon his two sons in part fulfilled; for he saw great-grandchildren from Ephraim; and grandchildren from one branch of Manasseh, Genesis 50:23 were brought up upon Joseph's knees; that is, according to the Chaldee, were brought up or educated by Joseph. The phrase seems to allude to the natural custom of dandling children upon the knees. Job, in ch. Genesis 3:12. says, Why did the knees prevent me? i.e.. Why was I sustained or dandled on the nurse's or midwife's knee? See ch. Genesis 30:3.
