This psalm shows a stark contrast between the wicked- 52:1-4- and the righteous- 52:6-9.
In vs. 5 four verbs are used to emphasize that God will bring the wicked down. The wicked are broken down, snatched up, torn away, and uprooted.
52:1-5 speaks in second person and addresses the ungodly man.
52:6-7 speak in third person describing the ungodly.
52:8-9 David speaks in first person and describes his trust in God's lovingkindness.
The psalm contrasts the ground of the wicked's trust (vs. 7) with the ground of the trust of the righteous (vs. 8).
The psalm uses an agricultural image to describe the judgment on the wicked (vs. 5) with an agricultural image to describe blessings upon the righteous (vs. 8).
