John Gill's Exposition of the Whole Bible
Proverbs 15:25
The Lord will destroy the house of the proud,.... To whom he has the utmost aversion; he sets himself against them and resists them, and will not only destroy them, but their stately houses too, which their have fancied shall continue for ever; and also their families, their children and posterity; these shall be as stubble, and shall be burnt up in his wrath, and neither root nor branch left. Moreover, the man of sin, the son of perdition, may be more especially intended, that exalts himself above all that is called God, with all the sons of pride supported by him; his house, which is the house of the foolish and adulterous woman, the idolatrous church of Rome, shall be rooted up; the city of Rome, the seat of the beast itself, where his house or palace is, shall be destroyed, and all that belong unto him, even all they that have destroyed the earth, Revelation 11:18;
but he will establish the border of the widow; whose advocate, judge, and defender he is; when men, rich, proud, and oppressive, attempt to remove the landmark of the widow's border, and so lessen her land and enlarge their own, God will not suffer it to be done, but will establish it in its place; that is, such who are weak and helpless, as widows are, and cannot defend themselves and their property, he will protect them and secure it for them. So the church of Christ, during the reign of antichrist, being obliged to flee into the wilderness, looks like a widow deprived of her husband, and has but "little strength" to support and defend herself, as is said of the church of Philadelphia, Revelation 3:8; yet the Lord will secure and preserve her, and firmly settle and establish her, yea, enlarge her borders, and make them of pleasant stones; spread the kingdom of Christ from sea to sea, and from the river to the ends of the earth. Frequent mention is made of the establishing of the church in the latter day, Psalms 48:8 Isaiah 2:2.
