The Magus: A Complete System of Occult Philosophy - Francis Barrett 1801

Of The Number Nine, and The Scale
The Magus, or Celestial Intelligencer

THERE are nine orders of blessed angels, viz. Seraphim, Cherubim, Thrones, Dominations, Powers, Virtues, Principalities, Archangels, and Angels, which Ezekiel figures out by nine stones, which are the sapphire, emerald, carbuncle, beryl, onyx, chrysolite, jasper, topaz, and sardis. This number hath also a great and occult mystery of the cross; for the ninth hour our Lord Jesus Christ breathed out his spirit. The astrologers also take notice of the number nine in the ages of men, no otherwise than they do of seven, which they call climacterical years, which are eminent for some remarkable change. Yet sometimes it signifies imperfectness and incompleteness, because it does not attain to the perfection of the number ten, but is less by one, without which it is deficient, as Austin interprets it of the ten lepers. Neither is the longitude of nine cubits of Og, King of Basan, who is a type of the devil without a mystery.
