How did he know, at the moment when the wise men of his day were saying that the earth was supported on the shoulders of a giant, that the giant stood on a platform made of the backs of elephants; that the elephants stood on the back of a mighty tortoise, but where the tortoise stood none of them said; how did he dare at that time to write that God hangeth the earth on nothing? How did Isaiah know that the world is round? How did he learn to speak of "the circle of the earth," at the time when the scientific men of his day said that it was four square and flat? How did he know of that imponderable ether in which the stellar universe is said to float? Who taught him to say that God spread out the heavens as "thinness," when the wise men of that hour were teaching they were a solid vault? How is it that he made use of the most scientific term when he speaks of the heavens as "thinness"? It is true in our English version he is made to say that God spread out the heavens as a "tent"; but the word "tent" in the Hebrew is (doq) and its root meaning signifies a thing that has been beaten out or stretched into thinness--an elastic thinness; it is a word accurately describing the ether which scientific men tell us is so thin that a teacup full of it may be blown out into a transparent bubble as large as the earth, and, even then, its attenuation would seem no greater than at the beginning. How did Isaiah know all this? Evidently his knowledge and wisdom did not come from the knowledge and wisdom of his day. That the Bible did not come from man is seen in the fact of fulfilled prohpecy. Page after page of this book is filled with prophetic announcements. History and human experience record their amazing fulfilment. The prophet Daniel gives the history of four great world empires, Babylon, Medo-Persia, Greece and Rome. The rise and fall of these empires are foretold centuries ahead. The total ruin and perpetual desolation of Babylon were announced when the city shone forth in the zenith of its splendor. Daniel writes an account of Alexander the Great two hundred and fifty years before he is born, calls him the first king of Greece, describes his march for the conquest of the East, the battle of the Grannicus, his sudden death at Babylon, and the division of the empire among his four generals.
