The blessed man is likened to a healthy and fruitful tree. As its success is the direct result of its nearness to the constant water source, so the blessed man thrives because he is ever near the necessary source of spiritual nourishment, the Law of the LORD. Those who spiritually thrive constantly abide in the Word of God. Remove yourself from the Word of God, and your soul shrivels up. Plant yourself by the Word of God, your soul will thrive.
The Righteous and the Wicked Contrasted.
How blessed is the man who does not walk in the counsel of the wicked, Nor stand in the path of sinners, Nor sit in the seat of scoffers! But his delight is in the law of the LORD, And in His law he meditates day and night. He will be like a tree firmly planted by streams of water, Which yields its fruit in its season And its leaf does not wither; And in whatever he does, he prospers.
The wicked are not so, But they are like chaff which the wind drives away. Therefore the wicked will not stand in the judgment, Nor sinners in the assembly of the righteous. For the LORD knows the way of the righteous, But the way of the wicked will perish.
