Job 35:16 Therefore doth Job open his mouth in vain; He multiplieth words without knowledge.Elihu accuses Job of running his mouth for nothing. He accuses Job of talking nonsense. I have been guilty of this so often over the years. I speak without the authority of Scripture. I give my opinion or one that I have heard and learned all my life only to find out I was wrong. It is so much better to speak only when God speaks and only to repeat what He says rather than saying things we will later be sorry for!
