'Branching' in the Bible

Israel is a branching vine, full of fruit; as his fruit is increased, so the number of his altars is increased; as the land is fair, so they have made fair pillars.

As for Ephraim, what has he to do with false gods any longer? I have given an answer and I will keep watch over him; I am like a branching fir-tree, from me comes your fruit.
