Job told his friends, when Eliphaz finished speaking, that if he could exchange places with. them, he could speak against them, and. shake his head at them, but lie would encourage them, and speak soothingly to them—the opposite of what they were doing to him.
But he turns away from the thought of his friends, to again consider God, and as in the tenth chapter, he even speaks against Him in wholly unbecoming language.
In verse 19 Job shows again that he knows God His Witness is in the heavens, and He that vouches for him (so it should read) is in the heights. Yet the need that only Christ could fill, is expressed in t verse 21.
