6:34 For jealousy [is] the rage of a man: therefore he will not {r} spare in the day of vengeance.
(r) He shows that man by nature seeks the death of he that has abused his wife, and so concludes that neither God's law nor the law of nature admits any ransom for the adultery.
6:34 Rage - It enflames a man with rage. In the day - When he hath an opportunity to avenge himself.
6:20-35 The word of God has something to say to us upon all occasions. Let not faithful reproofs ever make us uneasy. When we consider how much this sin abounds, how heinous adultery is in its own nature, of what evil consequence it is, and how certainly it destroys the spiritual life in the soul, we shall not wonder that the cautions against it are so often repeated. Let us notice the subjects of this chapter. Let us remember Him who willingly became our Surety, when we were strangers and enemies. And shall Christians, who have such prospects, motives, and examples, be slothful and careless? Shall we neglect what is pleasing to God, and what he will graciously reward? May we closely watch every sense by which poison can enter our minds or affections.
