The Hebrew word "bara," ordinarily translated "created," which implies to most people the idea of _creatio ex nihilo_, Ibn Ezra renders, in accordance with its etymology, to limit, to define, by drawing or incising a line or boundary. Having said this, Ibn Ezra, in his wonted mysterious manner, stops short, refusing to say more and preferring to mystify the reader by adding the tantalizing phrase, "The intelligent will understand." He means apparently to indicate that an eternal matter was endowed with form. In fact he seems to favor the idea of eternal creation and maintenance of the universe, the relation of which to God is as the relation of speech to the speaker, which exists only so long as the speaker speaks. The moment he ceases speaking the sounds cease to exist. The two ideas of eternal emanation of the world from God after the manner of the Neo-Platonists and of an eternal matter which God endows with forms, are not really quite consistent, for the latter implies that matter is independent of God, whereas according to the former everything owes its existence and continuance to God, from whom it emanates. But it is difficult from the fragmentary and laconic sayings of Ibn Ezra to extract a consistent and certain system. The world consists of three parts, three worlds Ibn Ezra calls them. The highest world consists of the separate Intelligences or angels, including the world-soul of which the human soul is a part. The intermediate world consists of the spheres, planets and fixed stars. Finally the lower world contains the four elements and the product of their various mixtures, minerals, plants, animals, man. These three worlds, Ibn Ezra appears to intimate in his oracular manner, are symbolized by the three divisions of the Tabernacle, the holy of holies typifying the world of spirits, the holy pointing to the spheres, while the outer court represents the sublunar world. The highest world, the world of Intelligences and angels, is eternal, though it too is dependent upon God for its existence. The angels, too, are composed of matter and form, and their function is to move the bodies of the intermediate world, the spheres and their stars. Through the instrumentality of the heavenly bodies, the angels form the lower world. This amounts to saying that the corporeal world is the last stage in the descending series of emanations from the One, and is preceded by the heavenly bodies and the Intelligences. The angels are also the immediate agents in prophetic inspiration. Not all mention of angels in the Bible, however, must be identified with a separate Intelligence or a spheral soul (for the latter too is called angel by Ibn Ezra). There are instances of the expression angel which refer to a momentary, special creation of a light or air for the special benefit of the people. This explains a number of theophanies in the Bible, such as the burning bush, "the glory of the Lord," the cloud in the wilderness, and so on.
