Job 13:19 - Ellicott's Commentary On The Whole Bible

If I hold my tongue, I shall give up the ghost. — A marvellous confession, equivalent to, “If I give up my faith in Him who is my salvation, and my personal innocence, which goes hand-in-hand therewith, I shall perish. To give up my innocence is to give up Him in whom I hold my innocence, and in whom I live.”
