Ephraim shall say, What have I to do any more with idols? This is full, final, and for over a renunciation of idolatry on the part of Israel. I have heard him, and observed him: I am like a green fir tree.
From me is thy fruit found. This is God's promise, that his eye is fixed on Israel in order to look after him, care for him, and provide for him, and to protect and prosper him; while the figure of a green fir tree is the pledge of shelter and security.
But, though the fir tree is evergreen, it is fruitless; and therefore it is added that God will prove the Source of fruitfulness, and supply all that his people shall or can ever need.
