Isaiah 48:7

They are created now... — The verb is an unusual one, as applied to the events of history. What is meant is that the things which had been from the beginning in the mind of God are now, for the first time, manifested, through the prophet, as about to pass into act. What these are the prophet develops in the following Chapter s, as including the spiritual redemption and restoration of Israel. They were kept in store, as it were, to make men wonder (Romans 16:25).

Even before the day when... — Better, and before to-day thou heardest them not.... The reason given for what we might almost call this method of reserve and reticence, was that the people had been till now unprepared to receive the truth, and in their state it would but have increased their condemnation (John 16:12; Mark 4:33).
