Ecclesiastes 10:8-15

He who digs a pit will fall into it, And whoever breaks through a wall will be bitten by a serpent. He who quarries stones may be hurt by them, And he who splits wood may be endangered by it. If the ax is dull, And one does not sharpen the edge, Then he must use more strength; But wisdom brings success. A serpent may bite when it is not charmed; The babbler is no different. The words of a wise man’s mouth are gracious, But the lips of a fool shall swallow him up; The words of his mouth begin with foolishness, And the end of his talk is raving madness. A fool also multiplies words. No man knows what is to be; Who can tell him what will be after him? The labor of fools wearies them, For they do not even know how to go to the city!
