For your iniquity teaches your mouth, and you choose the tongue of the crafty.
Job 15:5 · ESVView all translations

Eliphaz opens his second speech by turning Job's own words into evidence against him. Sin is teaching Job's mouth, he says, and the result is the talk of a schemer. Can a man's hasty words under crushing pain prove hidden guilt?

A harder tone in the second round

Eliphaz's tone has hardened since his first speech. The visit that began as sympathy has turned into a contest.

Job 15 records the second speech of Eliphaz, and we can hear a harsher tone in it. The friends had come to comfort Job, but their efforts soon turned into argument. Their tempers rose and bitterness spoiled their spirits, as each one argued to prove his own point of view. How often over the centuries has this tragedy ended in quarrels and division, and damaged the testimony of God-fearing people, right down to our own day.

The charge: guilt is dictating his speech

Job's iniquity, says Eliphaz, is the teacher behind his mouth. Yet he never quotes one sentence of Job's to prove it.

He tells Job that his own iniquity makes him speak as he does, and that Job chose crafty words to cover up his sin (v.5). Clearly Eliphaz was condemning Job, yet he claims that he is not the one condemning him — Job's own words are. He never tells Job which words condemned him. He simply uses this sweeping accusation to cancel everything Job had said. Of course this was deeply unfair, but he smugly insists, "Your own lips testify against you" (v.6).

"The tongue of the crafty": a false charge

The second half of the verse accuses Job of calculated speech — words chosen to hide something. Commentators grant that Job's language was wild, but they call this charge untrue.

Job had indeed left himself open to the charge of casting off fear. His language was wild, the opposite of prayer or devotion. His own words, says Eliphaz, confirm what the friends suspected and charged him with — wickedness and contempt for God. But when he accuses Job of craftiness, he charges what is untrue. The poor sufferer had poured out his misery with no thought for the consequences. Whatever else he is, Job is no hypocrite.

Samuel Ridout

Craft hides. Job hid nothing.

The danger of judging by the surface

The verse also warns the reader. Judging by what shows on the surface is the very trap this book was written to expose.

There could be no more instructive lesson for us about the danger of judging by appearances. It is beyond question a main point in this wonderful book. A quick look at the surface is never the way to reach a right judgment, as the Lord Himself warned in His day. If it was wrong in them then, it is far more blameworthy in us. Here we have a whole book given to guarding us from that trap… So in their judgment they saw nothing but a pretence in all Job's talk of longing to draw near to God, and in his confidence that God would clear him of the suspicion they had formed. They went far past the bounds of loving concern, and did not shrink from passing direct judgment.

William Kelly

God reads the same words differently

The book does not leave the question open. God weighs Job's words too, and He weighs them on a different scale from the friends.

What is it that God singles out as the right thing? On the surface of the book you might think Job had said as many wrong things about God as the rest of them. A hasty reader would even think Job spoke more rashly than Eliphaz and his two friends. But the truth is that the grace of God is far gentler than men suppose with the wild words a man lets slip under the pressure of a trial as terrible as Job's.

William Kelly

Eliphaz thought he was defending God's honour. The end of the book shows what that defence was worth.

They seemed to stand up for Him and defend His character. Yet under the searching gaze of the all-knowing God, who reads the hearts of men, they fall short. The charges they had brought against His servant Job were false.

Summary

- Comfort turned to contest. The friends came to console Job. Argument and rising tempers made Eliphaz's second speech harsh.

- Accusation without evidence. Eliphaz says Job's mouth condemns him, but never names one word. The sweeping charge cancels everything Job said.

- Craft was the false note. Job's words were wild, but he poured them out with no thought for the consequences. Whatever else he was, Job was no hypocrite.

- Surface reading fails. This book warns us not to judge by appearances. Appearances were against Job, and the verdict drawn from them was wrong.

- God's scale differs. He is gentler than men with words forced out by extreme trial. He called the friends' charges false, not Job's outbursts.
