Therefore doth Job open his mouth in vain; he multiplieth words without knowledge.
Ver. 16. Therefore doth Job open his mouth in vain] Dilatat, divaricat, rictum diducit ut bellua. An open mouth is oft a purgatory to the master; digito compesce labellum.
He multiplieth words without knowledge] Eliphaz had charged Job with malice and blasphemy, Job 22:1-30 Elihu, only with vanity and ignorance. We may not make the worst of things, but give a favourable interpretation.
