What Does Psalms 139:22 Mean?

I hate them with perfect hatred: I count them mine enemies. Perfect hatred (תַּכְלִית שִׂנְאָה, tachlit sin'ah) means complete, full, thorough hatred—David's opposition to God's enemies is total, not partial. This isn't emotional instability but principled conviction: those who are God's enemies become David's enemies because David has identified fully with God's cause. I count them mine enemies (לְאוֹיְבִים הָיוּ לִי, le-oyevim hayu li) shows deliberate choice: David consciously adopts God's judgments as his own.

This verse must be understood Christologically: Jesus perfectly embodied this principle by opposing Satan and spiritual evil with complete resolve while simultaneously dying for human enemies to make them friends (Romans 5:10). 'Perfect hatred' in the believer is directed at sin, Satan, and spiritual forces of wickedness—while maintaining redemptive love toward people enslaved by them. David's prayer culminates (vv. 23-24) by asking God to search his own heart, showing that holy hatred begins with self-examination.
