Peter's house - That Peter lived at Capernaum, and that Christ lodged with him, is fully evident from this verse compared with Matthew 17:24.

Peter's - wife's mother - Learn hence, says Theophylact, that marriage is no hinderance to virtue, since the chief of the apostles had his wife. Marriage is one of the first of Divine institutions, and is a positive command of God. He says, the state of celibacy is not Good, Genesis 2:18. Those who pretend to say that the single state is more holy than the other slander their Maker, and say in effect, "We are too holy to keep the commandments of God."

"He rose a great while before day;" and, when His secret communion was over, His public work began. It mattered not to Him where He was: whether on the bosom of the deep, or a mountain slope--in the desert, or at a well-side--the "gracious words" ever "proceeded out of His mouth." We find, on one touching …
