The books of the Old Testament were written at different times during the progress of this Early age of astronomy. We should therefore naturally expect to find the astronomical allusions written from the standpoint of such scientific knowledge as had then been acquired. We cannot for a moment expect that any supernatural revelation of purely material facts would be imparted to the writers of sacred books, two or three thousand years before the progress of science had brought those facts to light, and we ought not to be surprised if expressions are occasionally used which we should not ourselves use to-day, if we were writing about the phenomena of nature from a technical point of view. It must further be borne in mind that the astronomical references are not numerous, that they occur mostly in poetic imagery, and that Holy Scripture was not intended to give an account of the scientific achievements, if any, of the Hebrews of old. Its purpose was wholly different: it was religious, not scientific; it was meant to give spiritual, not intellectual enlightenment. An exceedingly valuable and interesting work has recently been brought out by the most eminent of living Italian astronomers, Prof. G. V. Schiaparelli, on this subject of "Astronomy in the Old Testament," to which work I should like here to acknowledge my indebtedness. Yet I feel that the avowed object of his book,[7:1]--to "discover what ideas the ancient Jewish sages held regarding the structure of the universe, what observations they made of the stars, and how far they made use of them for the measurement and division of time"--is open to this criticism,--that sufficient material for carrying it out is not within our reach. If we were to accept implicitly the argument from the silence of Scripture, we should conclude that the Hebrews--though their calendar was essentially a lunar one, based upon the actual observation of the new moon--had never noticed that the moon changed its apparent form as the month wore on, for there is no mention in the Bible of the lunar phases. The references to the heavenly bodies in Scripture are not numerous, and deal with them either as time-measurers or as subjects for devout allusion, poetic simile, or symbolic use. But there is one characteristic of all these references to the phenomena of Nature, that may not be ignored. None of the ancients ever approached the great Hebrew writers in spiritual elevation; none equalled them in poetic sublimity; and few, if any, surpassed them in keenness of observation, or in quick sympathy with every work of the Creator.
