4 the thought of the great voices returns. "Their line" is usually explained as meaning their sphere of influence, marked out, as it were, by a measuring cord. If that rendering is adopted, ver. 4 _b_ would in effect say, "Their words go as far as their realm." Or the rendering "sound" may be deduced, though somewhat precariously, from that of _line_, since a line stretched is musical. But the word is not used as meaning the string of an instrument, and the very slight conjectural emendation which gives "voice" instead of "line" has much to recommend it. In any case the teaching of the verse is plain from the last clause, namely the universality of the revelation. It is singular that the mention of the sun should come in the close of the verse; and there may be some error in the text, though the introduction of the sun here may be explained as completing the picture of the heavens, of which it is the crowning glory. Then follows the fuller delineation of his joyous energy, of his swift strength in his course, of his penetrating beams, illuminating and warming all. Why should the glowing metaphors, so natural and vigorous, of the sun coming forth from his bridal chamber and, hero-like, running his race, be taken to be traces of ancient myths now innocently reclaimed from the service of superstition? To find in these two images a proof that the first part of the psalm belongs to the post-exilic "literary revival of Hebrew mythology" is surely to lay more on them than they can bear. The scientific contemplation of nature is wholly absent from Scripture, and the picturesque is very rare. This psalmist knew nothing about solar spectra or stellar distances, but he heard a voice from out of the else waste heavens which sounded to him as if it named God. Comte ventured to say that the heavens declare the glory of the astronomer, not of God; but, if there be an order in them, which it is a man's glory to discover, must there not be a mind behind the order, and must not the Maker have more glory than the investigator? The psalmist is protesting against stellar worship, which some of his neighbours practised. The sun was a creature, not a god; his "race" was marked out by the same hand which in depths beyond the visible heavens had pitched a "tent" for his nightly rest. We smile at the simple astronomy; the religious depth is as deep as ever. Dull ears do not hear these voices; but whether they are stopped with the clay of earthly tastes and occupations, or stuffed with scientific wadding of the most modern kind, the ears that do not hear God's name sounded from the abysses above, have failed to hear the only word which can make man feel at home in nature. Carlyle said that the sky was "a sad sicht." The sadness and awfulness are taken away when we hear the heavens telling the glory of God. The unscientific psalmist who did hear them was nearer the very heart of the mystery than the scientist who knows everything else about them but that.
