For that would be a heinous crime; that would be an iniquity to be punished by the judges;
Job 31:11 · ESVView all translations

In his last speech Job swears that he is innocent of adultery. Here he names that sin for what it is — shameful in itself, and a crime for judges — though he lived long before God gave the law.

The setting: a closing oath of innocence

He is not claiming to be sinless before God. He is refusing his friends' charge that hidden wickedness explains his suffering.

Here, at the close of his last speech, Job makes his most solemn and complete declaration of innocence. He is not denying what he had already admitted about man's condition, his own included. But he flatly rejects the thought of grievous wickedness hidden under a fair exterior, which God might now be waging war against, as his friends had supposed.

William Kelly

On the charges his friends brought, his conscience was clear.

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 that were alleged or hinted at.

F. B. Hole

The sin he names

The "heinous crime" here is adultery with a neighbour's wife. Job adds a penalty to his denial. If he is lying, let his own home suffer the same wrong.

He returns to the subject he began with. He dwells on the sin of adultery against a neighbour (verses 9-12). In all this he was pure — willing to have his own home violated if it were not so. We get here a glimpse of his family life, equal in holiness to that of Isaac, Joseph, and the purest of the patriarchs.

Samuel Ridout

Right and wrong known before the law

Job lived before God gave the law. Yet he can call this act a crime for judges to punish.

This chapter shows that before God gave the law, God-fearing men still held a high standard of morality. That standard looked not only at the outward act but at the inward motive behind it. See the examples: he speaks of what he thought, or did not think, in verse 1; of his heart walking after his eyes, in verse 7; and of his heart enticed in secret, in verse 27.

F. B. Hole

The same writer lists what Job already knew to be wrong without any written commandment.

Again, he knew that deceit and false witness was wrong; see verse 5: that adultery was wrong; see verse 9: that idolatry was wrong; see verses 26-28; since the worship of sun and moon was the most primitive form that idolatry took.

F. B. Hole

Punished by the judges — and watched by God

Job does not stop at the human court. Judges could sentence him, and God watches every step he takes.

He judges unclean lusts as well as actions. He does this in the fear of Him who had power to cast soul and body into hell — Him who meanwhile took notice of all his steps. Trusting in gold, the covetousness the New Testament calls idolatry, was as hateful to his spirit as giving the highest lights in creation the glory due to God alone. In those early days that sin seems to have been just as clearly punishable before the judge as the sins of those who schemed to destroy another man's home. (Compare verses 9-11 with verses 26-28.)

William Kelly

The guard against this sin starts earlier, at the eye and the ear.

Set a strong guard around your outward senses. These are Satan's landing places, above all the eye and the ear. Take care what you take in through them; empty talk seldom passes without leaving some stain on the heart. And as for your eye, do not let it wander; impure objects cause impure thoughts. Job knew his eye and his thoughts were likely to go together, and so to secure the one he makes a covenant with the other.

Hamilton Smith

The flaw in a flawless defence

Job's record was true. The fault lay in the telling of it.

But we must take note of the self-righteousness that moved Job to speak of himself like this. He was putting himself on display instead of 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.

Samuel Ridout

Another writer weighs the speech as a whole.

He reviews his life to prove that he is clean in the sight of God and of man. But what are his declarations after all? Nothing but the filthy rags of his own righteousness — the empty boasting of a good, moral man, such as we hear on all sides.

Arno Clemens Gaebelein

Summary

- Covenant — Job's purity started at the eye. He made his agreement in advance, before temptation came.

- Crime — the act he refuses is adultery against a neighbour, and he stakes his own home on the truth of his denial.

- Conscience — Job knew this sin deserved punishment long before God gave the law. He judged the motive as well as the deed.

- Court — two courts sit over the same act: human judges who could sentence him, and God who counts every step he takes.

- Caution — the record was true, but Job put himself on display instead of giving God the glory.
