Chp.48 verses 10 -20: Yosef places his two sons between the knees of his father so that he can bless them. He places Manasseh, the first born, on his right and Ephraim, youngest, on his left. Yaakov crosses his hands so that his right hand in on the youngest and his left hand on the eldest. Yosef protests but Yaakov insists that he knows what he is doing. He blesses his grandsons with the famous blessing used to this day to bless Jewish boys.
