Psalms 109:11

Let the extortioner catch all that he hath; and let the strangers spoil his labour.

Psalm 109:11 belongs to an imprecatory psalm, a prayer that calls for judgment upon evildoers and stands among its fierce denunciations and prayers for the destruction of others. It belongs to a plea for divine justice in which those who plot wickedness against the innocent receive back the consequences of their own wrongdoing. Its words are inspired rather than uninspired personal additions, and the psalm as a whole is to be received as inspired.

The verse states a divinely spoken judgment against the wicked that the property of those deserving punishment will be seized and others will take the fruit of their labor. The psalm predicts God's retributive wrath upon evildoers as coming tribulation upon the enemies of God's church. Its imprecations declare God's retributive justice.

The punishment answers and fits the evil they sought to bring upon others. It is not David praying for personal revenge, nor a call for personal revenge or cruelty. Any apparent conflict between this passage and the Sermon on the Mount is not to be resolved by denying its inspiration.
