But the spirit of God is spoken of in one manner as being air flowing upon the earth, bringing a third element in addition

to water. In reference to which, Moses says, in his account of the creation of the world, "The spirit of God moved upon the face of the waters." Genesis i. 2. Since the air, as it is very light, is raised and borne aloft, having water, as it were, for its foundation; and, in another manner, unalloyed knowledge is said to be so, which every wise man naturally partakes of. And Moses shows us this, when speaking of the creator and maker of the holy work of the creation, in these words: "And God summoned Bezaleel, and filled him with his Holy Spirit, and with wisdom, and understanding, and knowledge, to be able to devise every work." Exodus xxxi 1. So that, what the spirit of God is, is very definitively described in these words.
