(3) I have declared . . .--Once more, for the seventh time, the prophet presses the fact of the Divine foreknowledge, not, as before, against the "no-faith" of the heathen, but against the "little faith" of Judah.

Verse 3. - I have declared the former things from the beginning (comp. Isaiah 41:26; Isaiah 43:9, 10; Isaiah 44:7, 8, etc.). "Former things" are here contrasted with the "new things" of ver. 6. Two cycles of prophecy seem to be intended - one of comparatively ancient date, the other quite fresh - both equally showing forth the power of God and his infinite superiority to the idols. It is difficult to determine what the two cycles of prophecy are. Delitzsch suggests that "the former things are the events experienced by the people from the very earliest times down to the times of Cyrus," while "the new things embrace the redemption of Israel from Babylon, the glorification of the people in the midst of a world of nations converted to the God of Israel, and the creation of a new heaven and a new earth." Dr. Kay thinks that the "former things" are those mentioned in the prophecies concerning Babylon generally, the "new things those about to be announced in Isaiah 49-56. I did them suddenly; rather, suddenly I wrought.

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.I have declared the former things from the beginning,.... From the time of their first ancestors, from the time of Abraham their father, to whom was declared what should befall his posterity; that they should sojourn in Egypt, be afflicted there, and come out from thence with great substance; that they be brought into the land of Canaan, and the inhabitants of it being driven out before them, Genesis 15:13.

And they went forth out of my mouth, and I showed them; they were told to Abraham by word of mouth; they were shown to him in prophecy:

I did them suddenly, and they came to pass; for very quickly these things began to take place, even in Abraham's time; for his seed being a stranger in a land not theirs, and afflicted near four hundred years, must be reckoned from the birth of Isaac; and all which exactly came to pass as was foretold; not one thing which the Lord had spoken of failed; all was punctually fulfilled, Joshua 21:45.
