(6) Thou hast heard . . .--The appeal is to the conscience of the exiles. They had heard the prediction. They are bidden to consider it all. Should not they declare the impression it had made on them?

I have shewed thee.--Better, I shew thee, as a present incipient act.

New things.--The "new things" are those that lie in a more distant future than the conquests of Cyrus, which are referred to as "former things."

Verse 6. - Thou hast heard, see all this; rather, thou didst hear, (now) see it all, i.e. see all the prophecies now fulfilled, which thou heardest in days gone by. Will ye not declare it? Will ye not for very shame make known generally the accordance between the prophecies and the events, which you cannot fail to see? Will ye not become "my witnesses" (Isaiah 43:10), and turn away from your idols? I have showed thee; rather, I show thee; i.e. "I am about to show thee from this time new things, even hidden things, which thou knowest not" - things belonging to the new cycle of prophecy, not previously announced, but reserved for the present crisis (see the comment on ver. 3). On the whole, the language used seems most consonant with the view of Dr. Kay, that the "new things" are those about to be revealed in the next section of the prophecy (Isaiah 49-53), things belonging to the coming of Christ, and the "new creation" which it will be the great object of his coming to bring about.

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.Thou hast heard, see all this: and will ye not declare it?.... You have heard of all these things, how they were foretold before they were; how they came to pass exactly as they were predicted; now look over these prophecies, and compare them with the events; see the exact completion of them; and when you have so done, can you be so stouthearted and impudent as to deny them, or not own and confess them?

I have showed thee new things from this time, even hidden things, and thou didst not know them; meaning the destruction of the Babylonish empire, and the deliverance of the Jews by Cyrus, prophesied just now in the preceding chapters; things not yet come to pass, newly revealed, which were hidden in the breast of God, and unknown to them until prophesied of; and which were typical of redemption by the incarnate Son of God, whose incarnation, and salvation by him, were new, unheard of, and wonderful things; and of the new state of things under the Gospel dispensation, when all things shall become new; the doctrines and ordinances of which are new; the whole Gospel is a hidden mystery, and unknown to men till revealed and made known by the Spirit of God.
