Psalm 39 -- This Psalm tells me a lot about the Lord and about myself. What is my conduct? Why should I guard it? The Bible speaks a lot about the tongue and what is said. The tongue is the only
instrument that gets sharper with use. David watches the wicked prosper and basically says, "I'm going to
watch my conduct with what I say, even retrain it with a muzzle while the wicked are before me."
