A man shall not be established by wickedness: but the {a} root of the righteous shall not be moved.

(a) They are so grounded in the favour of God, that their root will prosper continually.

Jamieson-Fausset-Brown Bible Commentary

3. Wickedness cannot give permanent prosperity.

root . not be moved-firm as a flourishing tree-(Ps 1:3; 15:5; Jer 17:8).

Matthew Henry's Concise Commentary

12:1 Those who have grace, will delight in the instructions given them. Those that stifle their convictions, are like brutes. 2. The man who covers selfish and vicious designs under a profession of religion or friendship, will be condemned. 3. Though men may advance themselves by sinful arts, they cannot settle and secure themselves. But those who by faith are rooted in Christ, are firmly fixed. 4. A wife who is pious, prudent, and looks well to the ways of her household, who makes conscience of her duty, and can bear crosses; such a one is an honour and comfort to her husband. She that is the reverse of this, preys upon him, and consumes him. 5. Thoughts are not free; they are under the Divine knowledge, therefore under the Divine command. It is a man's shame to act with deceit, with trick and design. 6. Wicked people speak mischief to their neighbours. A man may sometimes do a good work with one good word. 7. God's blessing is often continued to the families of godly men, while the wicked are overthrown. 8. The apostles showed wisdom by glorying in shame for the name of Christ. 9. He that lives in a humble state, who has no one to wait upon him, but gets bread by his own labour, is happier than he that glories in high birth or gay attire, and wants necessaries.
