The last chapter left us with the idea of the Lord chopping down the proud as if they were mighty trees.

Now the Lord is looking over the stumps and He causes a branch to grow out of one of them.

The root of the family of Jesse was the father, the royal authority of the house of David had lain dormant for 600 years.

When Jesus came forth it was like a green branch coming out of an apparently dead stump.

The Lord wanted Israel to know that even though Assyria would come and bring judgment, and they would be like stumps, that God was still going to bring life from them.

By saying that the root was from Jesse, God was emphasizing the much less humble father of King David.
