This verse is hard to understand unless you put it into context.
1 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 ! 2 But his delight is in the law of the LORD, And in His law he meditates day and night. 3 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. 4 The wicked are not so, But they are like chaff which the wind drives away. 5 Therefore the wicked will not stand in the judgment, Nor sinners in the assembly of the righteous. 6 For the LORD knows the way of the righteous, But the way of the wicked will perish.
It is during JUDGEMENT that the wicked do not prosper.
