Psalms 5:6 You destroy those who tell lies; Yahveh hates bloody and deceitful people.
The psalmist declares his faith in Yahveh as a God who does not tolerate those who attack with lies. Such people use falsehood as a weapon in order to get society to punish the people who stand in the way of their plans. But the psalmist knows that God knows the truth. He will destroy the ones who use their tongues to destroy the innocent.
