What does Psalm 139:21 mean?
What is the meaning of Psalm 139:21?

Do I not hate those

Psalm 139:21 opens with David’s rhetorical question, signaling deep personal alignment with God. His “hate” is covenant loyalty—a deliberate rejection of anything opposed to the Lord’s character. This is the same moral stance seen in Psalm 97:10, “Hate evil, O you who love the LORD,” and Romans 12:9, “Abhor what is evil; cling to what is good.”

• David is not venting uncontrolled anger; he is voicing a conscious, moral revulsion toward sin and rebellion.

• Such hatred flows from loving what God loves and therefore refusing fellowship with darkness (Ephesians 5:11).

• We are reminded that friendship with the world’s godless system is enmity with God (James 4:4).


who hate You, O LORD

The focus shifts to the object: “those who hate You.” David’s concern is not personal offense but God’s honor. In 1 Samuel 17:45–47 he displayed the same zeal against Goliath, declaring the battle belongs to the LORD.

• God’s enemies are identified by their deliberate hostility toward Him, as in Exodus 20:5 where idolaters are called “those who hate Me.”

• David’s heart echoes Moses’ call in Deuteronomy 30:19–20 to choose life by loving and obeying God.

• The passage teaches believers today to discern between opposition against ourselves and opposition against God’s rule (John 15:18–19).


and detest those

The parallel verb “detest” intensifies the previous line, underscoring an uncompromising stance. Proverbs 8:13 says, “To fear the LORD is to hate evil,” tying reverent worship to moral rejection of wickedness.

• Detestation here is principled: it arises from reverence, not prejudice.

• It mirrors the call in Jude 23 to “hate even the clothing stained by corrupted flesh” while showing mercy to individuals—compassion without compromise.

• David’s language also anticipates Jesus’ teaching that loyalty to Him may require severing allegiance to what opposes Him (Matthew 10:37–38).


who rise against You?

The final clause pictures active rebels—those who “rise” in defiance. In Psalm 2:1–3 the nations rage and rulers band together “against the LORD and against His Anointed,” illustrating the same posture.

• David identifies with God’s cause, not with insurgents who attempt to overthrow His authority (Numbers 16:28–35’s Korah rebellion).

• The New Testament applies this principle spiritually: 2 Corinthians 10:5 calls believers to demolish arguments that set themselves up against the knowledge of God.

• While David expresses detestation, Christ’s followers are also instructed to love enemies personally (Matthew 5:44) even as they stand firm against spiritual rebellion (Ephesians 6:12). Holding both truths—love for persons and hatred of sin—protects us from either compromise or cruelty.


summary

Psalm 139:21 voices David’s fierce loyalty to God: he consciously rejects, opposes, and separates himself from those who knowingly oppose the LORD. This “hate” is not vindictive rage but a principled, covenantal allegiance that refuses fellowship with evil while upholding God’s honor. Believers today echo that stance by detesting sin, resisting rebellion, and yet extending Christlike love to individual enemies—honoring God with uncompromised hearts.
