For they call themselves of the holy city, and stay themselves {c} upon the God of Israel; The LORD of hosts is his name.

(c) They make a show, as though they would have no other God.

Wesley's Notes

48:2 Though - They glory that they are citizens of Jerusalem, a city sanctified by God, to be the place of his true worship, and gracious presence. And stay - Not by a true faith, but a vain confidence.

Jamieson-Fausset-Brown Bible Commentary

2. For-Ye deserve these reproofs; "for" ye call yourselves citizens of "the holy city" (Isa 52:1), but not in truth (Isa 48:1; Ne 11:1; Da 9:24); so the inscription on their coins of the time of the Maccabees. "Jerusalem the Holy."

Matthew Henry's Concise Commentary

48:1-8 The Jews valued themselves on descent from Jacob, and used the name of Jehovah as their God. They prided themselves respecting Jerusalem and the temple, yet there was no holiness in their lives. If we are not sincere in religion, we do but take the name of the Lord in vain. By prophecy they were shown how God would deal with them, long before it came to pass. God has said and done enough to prevent men's boasting of themselves, which makes the sin and ruin of the proud worse; sooner or later every mouth shall be stopped, and all become silent before Him. We are all born children of disobedience. Where original sin is, actual sin will follow. Does not the conscience of every man witness to the truth of Scripture? May the Lord prove us, and render us doers of the word.
