Isaiah 48:7

7.Now for the first time have they been created. The Prophet shews that he is not reasoning about things that are known, or that have been learned by actual experience; and his object is, not merely to correct that haughtiness which is natural to all men, (for they claim for themselves what belongeth to God alone,) but likewise that no part of this event may be ascribed to fortune or to any other cause. In various ways do men rob God of the glory that is due to him, and direct all their faculties towards distributing among the creatures that which belongs to Him alone, so as to leave Him nothing but a bare and empty name. That the people might not think that they had been vanquished by the power of the Babylonians, or that it was by human strength or by chance that they were afterwards restored to liberty, on this account he so frequently repeats and reiterates, that this is the work of God.

Thou hadst not heard those things. When he affirms that “they had not heard them,” some explain this to mean that the people rejected God’s warnings, and did not listen to good counsels. But I think that the Prophet’s meaning was different, namely, that what could not be known by human sagacity, and what had been unknown to the Jews, has been revealed in such a manner that they cannot defraud the Holy Spirit of the praise which is due to him; and this is very evident from the context.
