This beloved psalm, which was most likely intended as an introduction to the entire Psalter, clearly sets out that there are two types of people—the godly and the ungodly. The godly are firmly grounded in the law of the Lord, for it is their delight. The ungodly, however, have no grounding at all, but “are like the chaff, which the wind driveth away.”
Blessed is the man
that walketh not in the counsel of the ungodly,
nor standeth in the way of sinners,
nor sitteth in the seat of the scornful.
But his delight is in the law of the Lord;
and in his law doth he meditate day and night.
And he shall be like a tree planted by the rivers of water,
that bringeth forth his fruit in his season;
his leaf also shall not wither;
and whatsoever he doeth shall prosper.
The ungodly are not so:
but are like the chaff which the wind driveth away.
Therefore the ungodly shall not stand in the judgment,
nor sinners in the congregation of the righteous.
For the Lord knoweth the way of the righteous:
but the way of the ungodly shall perish.
