481 "And now listen to this, family of Jacob, you who are called by the name Israel: Who got you started in the loins of Judah, you who use God's name to back up your promises and pray to the God of Israel? But do you mean it? Do you live like it? 2 You claim to be citizens of the Holy City; you act as though you lean on the God of Israel, named God-of-the-Angel-Armies. 3 For a long time now, I've let you in on the way I work: I told you what I was going to do beforehand, then I did it and it was done, and that's that. 4 I know you're a bunch of hardheads, obstinate and flint-faced, 5 So I got a running start and began telling you what was going on before it even happened. That is why you can't say, 'My god-idol did this.' 'My favorite god-carving commanded this.'
Matthew Henry's Commentary on Isaiah 48:1-5
Commentary on Isaiah 48:1-8
(Read Isaiah 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.
