the prophecy of Joseph

22 Joseph is a fruitful bough, even a fruitful bough by a well; whose branches run over the wall:

23 The archers have sorely grieved him, and shot at him, and hated him:

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:)


Does the shepherd, the stone of Israel come from God or Joseph?
