481 “Hear this, house of Jacob, you who are called by the name of Israel, and have come forth out of the waters of Judah; who swear by the name of Yahweh, and make mention of the God of Israel, but not in truth, nor in righteousness 2 (for they call themselves of the holy city, and stay themselves on the God of Israel; Yahweh of Armies is his name): 3 I have declared the former things from of old; yes, they went forth out of my mouth, and I showed them: suddenly I did them, and they happened. 4 Because I knew that you are obstinate, and your neck is an iron sinew, and your brow brass; 5 therefore I have declared it to you from of old; before it came to pass I showed it to you; lest you should say, ‘My idol has done them, and my engraved image, and my molten image, has commanded them.’
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.
