6 Thou hast heard, see all this; and will not ye declare it? I have shewed thee new things from this time, even hidden things, and thou didst not know them.
6 You have heard these things; look at them all. Will you not admit them? "From now on I will tell you of new things, of hidden things unknown to you.
6 "You have heard; now see all this; and will you not declare it? From this time forth I announce to you new things, hidden things that you have not known.
6 You have all this evidence confirmed by your own eyes and ears. Shouldn't you be talking about it? And that was just the beginning. I have a lot more to tell you, things you never knew existed.
6 "You have heard; See all this. And will you not declare it? I have made you hear new things from this time, Even hidden things, and you did not know them.
6 You have heard my predictions and seen them fulfilled, but you refuse to admit it. Now I will tell you new things, secrets you have not yet heard.
Matthew Henry's Commentary on Isaiah 48:6
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.
