Job 31:10

After these sorrowful complaints, Job closed his long speech, as we see in Job 31. He ended with a series of strong declarations that almost amount to oaths. His friends had accused him of definite sins and wrongdoing. As to these things his conscience was clear, though, as we have seen, he admitted he was not pure in the sight of God. So he strongly affirmed that he had not committed the kinds of evil they alleged or hinted at.

Job opens this sevenfold protest of purity and integrity. He dwells on a side of his character and conduct that even his friends had not openly challenged. They had hinted at general wickedness — turning away from God, violent dealings with the needy and others. But they had never touched the subject of personal purity.

In all this he was pure — willing to have his own home violated if this were not so. Here we get a glimpse of his family life, as holy as that of Isaac, Joseph, and the purest of the patriarchs.

Men might draw their conclusions from appearances. Job could still ask God to weigh him in a just balance, and to see whether he had used deceit or turned aside from the way. If he had, then let another reap the results of his labour. And let punishment reach even his own wife for such consuming evil on his part.

Again, he insists. Suppose a woman had enticed his heart. Suppose he had taken the first step in going to his neighbour's house with evil motives. Then let his wife leave him and choose another. "For," he says, "that would be wickedness, deserving of judgment. For that would be a fire that consumes to destruction, and would root out all my increase" (vv. 11-12). He had no doubt about the wickedness of such things, even though many careless people today think otherwise.

Job had shut his eyes, the way into the heart, by a settled purpose — a "covenant" against even a look at what might stir up passion. In the Sermon on the Mount our Lord showed that real purity must lie in the heart. It is not just a matter of outward restraint (Matt. 5:27-28)… "How can I do this great wickedness and sin against God?" said Joseph when the temptress came at him (Gen. 39:9). In an hour of spiritual sloth, David had let his eyes wander, and had fallen (2 Sam. 11:2).

This chapter shows that before God gave the law, a high standard of morality was still found among God-fearing men. That standard looked not only at the outward act but also at the inward motive behind the act.

But we must take note of the self-righteousness that moved Job to speak of himself like this. He was putting himself on display rather than giving glory to God. No doubt at bottom he was a man of genuine piety, but it is no glory to set out one's own glory.
