Genesis 47:7 - Ellicott's Commentary On The Whole Bible

Jacob blessed Pharaoh. — The presentation of Jacob to Pharaoh seems to have been a much more solemn matter than that of Joseph’s brethren. Pharaoh looks upon them with interest as the brothers of his vizier, grants their request for leave to dwell in Goshen, and even empowers Joseph to make the ablest of them chief herdsmen over the royal cattle. But Jacob had attained to an age which gave him great dignity: for to an Egyptian 120 was the utmost limit of longevity. Jacob was now 130, and Pharaoh treats him with the greatest honour, and twice accepts his blessing. More must be meant by this than the usual salutation, in which each one presented to the king prayed for the prolongation of his life. Pharaoh probably bowed before Jacob as a saintly personage, and received a formal benediction.
