Ecclesiastes 10:8-15

Anyone who digs a pit might fall into it; anyone who knocks down a wall might be bitten by a snake; anyone who moves boulders might be hurt by them; and anyone who cuts logs might be harmed by them. A dull ax means harder work. Being wise will make it easier. If a snake bites the tamer before it is tamed, what good is the tamer? The words of the wise bring them praise, but the words of a fool will destroy them. A fool begins by saying foolish things and ends by saying crazy and wicked things. A fool talks too much. No one knows the future, and no one can tell what will happen after death. Work wears fools out; they don’t even know how to get home.
