My brethren That is, my kinsmen, or three friends; for though Eliphaz only had spoken, the other two had shown their approbation of his discourse; have dealt deceitfully Under a pretence of friendship dealing unmercifully with me, and adding to the afflictions which they said they came to remove. As the stream of brooks, &c. Which quickly vanish and deceive the hopes of the thirsty traveller. It is no new thing for even brethren to deal deceitfully. It is therefore our wisdom to cease from man. We cannot expect too little from the creature, or too much from the Creator.
