+Psalm 52God Judges the Proud
+
+1. Why boast about evil, you hero!
+God's faithful love is constant.
+
+2. Like a sharpened razor,
+your tongue devises destruction,
+working treachery.
+
+3. You love evil instead of good,
+lying instead of speaking truthfully.Selah
+
+4. You love any words that destroy,
+you treacherous tongue!
+
+5. This is why God will bring you down forever.
+He will take you, ripping you out of your tent;
+he will uproot you from the land of the living.Selah
+
+6. The righteous will see and fear,
+and they will derisively say about that hero,
+
+7. "Here is the man
+who would not make God his refuge,
+but trusted in the abundance of his riches,
+taking refuge in his destructive behavior."
+
+8. But I am like a flourishing olive tree
+in the house of God;
+I trust in God's faithful love forever and ever.
+
+9. I will praise you forever 
+for what you have done.
+In the presence of your faithful people,
+I will put my hope in your name, for it is good.
