Sec. 5. Now, with respect to this whole chapter, we must remember always that it is intended for the instruction of all mankind, not for the learned reader only; and that, therefore, the most simple and natural interpretation is the likeliest in general to be the true one. An unscientific reader knows little about the manner in which the volume of the atmosphere surrounds the earth; but I imagine that he could hardly glance at the sky when rain was falling in the distance, and see the level line of the bases of the clouds from which the shower descended, without being able to attach an instant and easy meaning to the words "Expansion in the midst of the waters." And if, having once seized this idea, he proceeded to examine it more accurately, he would perceive at once, if he had ever noticed _anything_ of the nature of clouds, that the level line of their bases did indeed most severely and stringently divide "waters from waters," that is to say, divide water in its collective and tangible state, from water in its divided and aerial state; or the waters which _fall_ and _flow_, from those which _rise_ and _float_. Next, if we try this interpretation in the theological sense of the word _Heaven_, and examine whether the clouds are spoken of as God's dwelling place, we find God going before the Israelites in a pillar of cloud; revealing Himself in a cloud on Sinai; appearing in a cloud on the mercy seat, filling the Temple of Solomon with the cloud when its dedication is accepted; appearing in a great cloud to Ezekiel; ascending into a cloud before the eyes of the disciples on Mount Olivet; and in like manner returning to Judgment. "Behold, he cometh with clouds, and every eye shall see him." "Then shall they see the son of man coming in the clouds of heaven, with power and great glory."[38] While farther, the "clouds" and "heavens" are used as interchangeable words in those Psalms which most distinctly set forth the power of God: "He bowed the heavens also, and came down; he made darkness pavilions round about him, dark waters, and thick clouds of the skies." And, again: "Thy mercy, oh Lord, is in the heavens, and thy faithfulness reacheth unto the clouds." And, again: "His excellency is over Israel, and his strength is in the clouds." Again: "The clouds poured out water, the skies sent out a sound, the voice of thy thunder was in the heaven." Again: "Clouds and darkness are round about him, righteousness and judgment are the habitation of his throne; the heavens declare his righteousness, and all the people see his glory."
