'Roots' in the Bible

Therefore, as a tongue of fire consumes strawand as dry grass shrivels in the flame,so their roots will become like something rottenand their blossoms will blow away like dust,for they have rejectedthe instruction of the Lord of Hosts,and they have despisedthe word of the Holy One of Israel.

Then a shoot will grow from the stump of Jesse,and a branch from his roots will bear fruit.
