TNDL: “WHO ARE THOSE PEOPLE that are blessed, and they who are cursed, according to psalm 1?”

Psalm 1 New King James Version (NKJV)
BOOK ONE
Psalms 1–41
The Way of the Righteous and the End of the Ungodly
1 Blessed is the man
Who walks not in the counsel of the [a]ungodly,
Nor stands in the path of sinners,
Nor sits in the seat of the scornful;
2 But his delight is in the law of the Lord,
And in His law he [b]meditates day and night.
3 He shall be like a tree
Planted by the [c]rivers of water,
That brings forth its fruit in its season,
Whose leaf also shall not wither;
And whatever he does shall prosper.
4 The ungodly are not so,
But are like the chaff which the wind drives away.
5 Therefore the ungodly shall not stand in the judgment,
Nor sinners in the congregation of the righteous.
6 For the Lord knows the way of the righteous,
But the way of the ungodly shall perish.
