'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.

And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots:

And the remnant of the house of Judah that remain shall {grow} roots downwards and make fruit upwards.
