Job 31:29

If I rejoiced at the destruction of him that hated me,.... Job, though a good man, had his enemies, as all good men have, and that because of their goodness, and who hated him with an implacable hatred, without a cause, there being a rooted bitter enmity in the seed of the serpent against the godly in all generations; on whom sooner or later, at one time or another, destruction comes, one calamity or another on their families, diseases on their bodies, loss of substance, death of themselves or relatives; now it is a common thing with wicked men to rejoice in the adversity of their enemies, but good men should not do so; yet it is a difficult thing, and requires a large measure of grace, and that in exercise, not to feel any pleasing emotion, a secret joy and inward pleasure, at the hearing of anything of this sort befalling an enemy; which is a new crime Job purges himself from:

or lifted up myself when evil found him; either the evil of sin, which sooner or later finds out the sinner, charges him with guilt, and requires punishment, or the evil of punishment for sin; which, though it may seem to move slowly, pursues the sinner, and will overtake him, and light upon him. Mr. Broughton renders the words, "and bestirred me when he found loss": loss in his family, in his cattle, and in his substance; now, when this was the case, Job did not raise up himself in a haughty manner, and insult and triumph over him, or stir up himself to joy and rejoicing, or to make joyful motions, as Aben Ezra and Ben Gersom interpret it; and by his gestures show that he was elated with the evil that had befallen his enemy; indeed so far as the fall and destruction of the wicked make for the public good, for the interest of religion, for the glory of God, and the honour of his justice, it is lawful for good men to rejoice thereat; but not from a private affection, or from a private spirit of revenge, see Psalms 58:10.
