Isaiah 40:21 - Exposition

Have ye not known? Hitherto the prophet has restrained himself, and confined himself to quiet sarcasm. Now he bursts out. Is there any one so insensate, so devoid of natural reason and understanding, as not to know what has been known to all from the beginning—yea, from the foundations of the earth—by "the light that is in them," viz. that God is something wholly different from this?—that he is such a One as the prophet proceeds to describe in Isaiah 40:22-24 , alike above nature and above man, Lord of heaven and earth, and absolute Disposer of the fates of all men? Hath it not been told you? If ye have not known the nature of God by the light of nature, has it not come down to you by tradition? Have not your fathers told it you? Has it not been handed on by sire to son from the very foundation of the earth? The appeal is to men generally, not especially to Israel. Have ye not understood, etc.? Some omit the preposition after "understood," and render the passage thus: "Have ye not understood the foundations of the earth?" i.e. how it was founded, or created—that its creation was God's sole act? (so the LXX ; the Vulgate, Gesenius, Hitzig, Delitzsch, Knobel, Kay; but Ewald, Henderson, Weir, and Mr. Cheyne prefer the rendering of the Authorized Version).
