Jacob’s Blessings
Question
Why did Jacob, when blessing all of his sons, bless them out of their birth order? He doesn't even bless them in the order of their mothers like it might seem, as all of Leah's children are blessed first and all of Rachel's are blessed last. Bilhah and Zilpah's children are not blessed in groups, but rather Zilpah's children are blessed between the birth of Bilhah's two children. Also, Leah's last two children are blessed out of birth order. Is there a midrash on this somewhere? I'm sure it must be based on Jacob's previous blessings of Joseph's children out of order, but I cannot seem to find it. Thank you.
