Ecclesiastes 5:2-5

Don’t shoot off your mouth, or speak before you think. Don’t be too quick to tell God what you think he wants to hear. God’s in charge, not you—the less you speak, the better. Overwork makes for restless sleep. Overtalk shows you up as a fool. When you tell God you’ll do something, do it—now. God takes no pleasure in foolish drivel. Vow it, then do it. Far better not to vow in the first place than to vow and not pay up.
