"I will give thanks to the Lord because of his righteousness; I will sing the praises of the name of the Lord Most High." (Psalm 7:17)
Psalm 7 is a prayer of someone who has been falsely accused. David calls it a shiggaion, a term that may indicate an irregular or passionate rhythm, a prayer that bursts out of its formal container under the pressure of unjust accusation. He takes refuge in God and pleads his innocence: Lord my God, if I have done this and there is guilt on my hands, if I have repaid my ally with evil or without cause have robbed my foe, then let my enemy pursue and overtake me. He invites God to judge him by his actual conduct, not by the slander of his enemies.
This willingness to stand before God's scrutiny is itself an act of faith. The person with a guilty conscience cannot pray this prayer. David prays it because he knows his own heart on this particular matter and trusts that God's judgment will vindicate him. The Catechism notes that the examination of conscience before the Lord is the beginning of all genuine prayer: to stand before God as we actually are, hiding nothing (CCC 1454).
The centre of the psalm is a meditation on God as judge. He tests minds and hearts. He is a righteous God. His anger is provoked by the wicked every day. The one who plots evil will find that it falls back on his own head. David uses a vivid image: the wicked person digs a hole and falls into the pit they have made. The violence they planned returns on their own head. This is not David's curse on his enemies. It is his observation of the moral structure of reality: wickedness carries its own punishment within it.
St. John Chrysostom preached that the righteous judge of Psalm 7 is the same judge before whom every person will stand at the last day. The interim injustices of this life, the false accusations, the slanders, the unpunished wrongs, will all be addressed. The Christian who has been falsely accused can pray Psalm 7 with the confidence that the final verdict belongs to God, not to human opinion.
The psalm ends not with a curse on enemies but with thanksgiving: I will give thanks to the Lord because of his righteousness; I will sing the praises of the name of the Lord Most High. The distress of the falsely accused resolves not in vindication already received but in the anticipation of God's righteousness being demonstrated. The praise comes before the verdict is publicly announced, because trust in God's justice does not wait for external confirmation.
Brothers and sisters, few things are more painful than being falsely accused. Psalm 7 does not offer easy comfort, but it offers the most reliable comfort: bring it before the righteous judge. Let God examine your heart. And then sing praise in advance of the verdict, because the one who judges is also the one who saves.
Lord Most High, you are the righteous judge who searches minds and hearts. When I am falsely accused, let me take refuge in you. Vindicate me in your righteousness, and whether the vindication comes in this life or the next, give me the grace to praise you already. Through Christ our Lord. Amen.
