Genesis 49:24

but his bow abode in strength, and the arms of his hands were made strong by the hands of the mighty God of Jacob (from thence is the Shepherd, the Stone of Israel). Here the powerful and victorious growth of the tribes of Ephraim and Manasseh is pictured, in consequence of which all enemies would be overcome. This result, however, would not come about by their own power, but through the help of the mighty God of Jacob, by virtue of the assisting hands of God, who is both the Shepherd and the Rock of Israel.
