9. Now this world is encompassed by seven heavens,26 in which dwell powers and angels and |78 archangels, doing service to God, the Almighty and Maker of all things: not as though He was in need, but that they may not be idle and unprofitable and ineffectual.27 Wherefore also the Spirit of God is manifold in (His) indwelling,28 and in seven forms of service 29 is He reckoned by the prophet Isaiah, as resting on the Son of God, that is the Word, in His coming as man. The Spirit of God, he says, shall rest upon him, the Spirit of wisdom and of understanding, the Spirit of counsel and of might, (the Spirit of knowledge) and of godliness; the Spirit of the fear of God shall fill him.30 Now the heaven which is first from above,31 and encompasses the rest, is (that of) wisdom; and the |79 second from it, of understanding; and the third, of counsel; and the fourth, reckoned from above, (is that) of might; and the fifth, of knowledge; and the sixth, of godliness; and the seventh, this firmament of ours, is full of the fear of that Spirit which gives light to the heavens. For, as the pattern (of this), Moses received the seven-branched candlestick, that shined continually in the holy place; for as a pattern of the heavens he received this service, according to that which the Word spake unto him: Thou shalt make (it) according to all the pattern of the things which thou hast seen in the mount.32
26. 1 An account of the late Jewish teaching as to the Seven Heavens is given in Mr. H. St John Thackeray's valuable book St Paul and Contemporary Jewish Thought, pp. 172-179, where three parallel tables of their descriptions will be found. References to them in Christian apocryphal literature are collected in Dr Charles's Book of the Secrets of Enoch (from the Sclavonic), pp. xliv-xlvii. Hippolytus in his Commentary on Daniel (ed. Achelis, p. 96), referring to ... in the Benedicite, says: ... . Clement of Alexandria (Strom, iv. 25) says: ..., Origen (c. Cels, vi. 21) likewise mentions the Seven Heavens, but without committing himself to the exact number.
