Psalms 1:4

“The ungodly [are] not so, etc.] They are not as the good man is; their manner and course of life are different; they walk in the counsel of ungodly men, like themselves, and take counsel against the Lord, his Anointed, and his people: they stand in the way of sinners, and steer their conversation according to the course of the world, and sit in the seat of the scornful; laugh at divine revelation, lampoon the Scriptures, deride good men, make a jest of religion and a future state: they have no delight in the law of the Lord, they cast it away from them, and despise it; and are so far from a constant meditation on it, that they never read it, nor so much as look into it, nor is it ever in…”

“not so--either as to conduct or happiness. like the chaff--which, by Eastern modes of winnowing against the wind, was utterly blown away.”

“The ungodly are not so - literally, “Not thus the wicked.” For the word ungodly, see the notes at Psalms 1:1. The statement that the “wicked are not so,” is a general statement applicable alike to their character and destiny, though the mind of the author of the psalm is fixed immediately and particularly on the difference in their destiny, without specifying anything particularly respecting their character. It is as true, however, that the ungodly do walk in the counsel of the wicked, and stand in the way of sinners, and sit in the seat of the scornful, as it is that the righteous do not; as true that they do not delight in the law of the Lord, as it is that the righteous do; as true that…”

“1:4 The coming time of judgment (1:5) will carry off the wicked and their deeds (35:5; 83:13; Isa 17:13; see study note on Jer 13:24).”

“like: Psa 35:5; Job 21:18; Isa 17:13, Isa 29:5; Hos 13:3; Mat 3:12 Psalms 1:5”

“The ungodly (הרשׁעים, with the demonstrative art.) are the opposite of a tree planted by the water-courses: they are כּמּץ, like chaff (from מוּץ to press out), which the wind drives away, viz., from the loftily situated threshing-floor ( Isa 17:13), i.e., without root below, without fruit above, devoid of all the vigour and freshness of life, lying loose upon the threshing-floor and a prey of the slightest breeze-thus utterly worthless and unstable. With על־כּן an inference is drawn from this moral characteristic of the ungodly: just on account of their inner worthlessness and instability they do not stand בּמּשׁפּט. This is the word for the judgment of just recompense to which God brings…”
