Psalms 109:20

Let this be the reward of mine adversaries from the LORD, and of them that speak evil against my soul.

Psalm 109 is one of the imprecatory psalms, marked by fierce denunciations and prayers for the destruction of others. It concerns judgment upon the enemies of God's people. More particularly, it has in view those who plot wickedness against the innocent and speak evil against the soul, calling for them to receive the consequences of their own wrongdoing.

The reward called for is retributive justice, in which the adversaries' own hostile words and actions are made to return upon them as their recompense. The punishments they sought to bring upon others come upon themselves. In this way the verse predictively declares tribulation and God's retributive wrath upon evil-doers. It expresses God's just judgment on the wicked and stands as God's own declaration against those whose lives are evil.

It is not an expression of personal revenge nor an encouragement to commit cruelty. Nor is it David asking God to curse his personal enemies. It is a plea for divine justice and a prayer that brings the distress of the soul before the Lord.
