A man shall not be established by wickedness: but the root of the righteous shall not be moved.
– Proverbs 12:3
A root anchors and stabilizes the tree. Having a good root means flourishing in fruit and strength to withstand storms and so to endure. There is no such root in wickedness. The word for established means to stand upright. Righteousness, on the contrary, will establish a man that he not be moved (Proverbs 10:25).
