Job 31:29 - Matthew Poole's English Annotations on the Holy Bible

I was so far from malice and revenging myself of mine enemy, which is the common and allowed practice of ungodly men, that I did not so much as desire or delight in his ruin, when it was brought upon him by other hands. Compare Exodus 23:4 Proverbs 24:17,18. Whence we may judge whether the great duty of loving and forgiving our enemies be a peculiar precept of Christianity, or whether it be a natural and moral duty, and a part and act of that charity which now is, and ever was, the duty of one man to another in all ages. Lifted up myself, Heb. stirred up myself, to rejoice and insult over his misery.
