Shared ground
Psalm 4:2 shifts from speaking to God (v.1) to confronting a human group (“sons of men”). The speaker claims these people have been actively undermining him over time (“how long”), specifically by turning his “glory” into disgrace. He also describes the inner pull and outward strategy behind their behavior: they “love” what is empty and “seek” what is false. The verse ends with “Selah,” a deliberate pause that lets the accusation stand.
Where interpretation differs (only where needed)
Who is being addressed (“sons of men”): Some read it as a rebuke aimed at powerful people (leaders, nobles, decision-makers) who can publicly damage someone’s standing. Others take it more broadly as a general address to people who oppose the speaker.
What “my glory” refers to: Some understand it mainly as the speaker’s public reputation and social honor. Others think it points more narrowly to the dignity of his role (for example, leadership legitimacy). A further option is that it includes both—his standing as a person and the recognized worth of his position.
What “falsehood” and “vanity” describe: Some read these as primarily about deceptive speech (rumors, lies, smear tactics). Others understand them as empty plans and misguided pursuits, which may include deceitful talk but is not limited to it.
Why the disagreement exists
The Hebrew phrases are short and flexible: “sons of men” can be a general description or a pointed address, and “glory” can mean personal honor, recognized worth, or dignity tied to office. Likewise, “vanity” (emptiness) and “falsehood” can describe both words and plans. The verse itself does not specify the exact social setting.
What this passage clearly contributes
Explicitly, the text presents dishonoring another person as something that can be sustained over time and driven by misdirected desire (“love vanity”) and intentional pursuit (“seek falsehood”). It also shows a pattern in the psalm: appeal to God does not replace honest naming of human wrongdoing; it is followed by direct moral clarity about what the opponents are doing (Psalm 4:2).
