appears as impossible as that of walking without legs; for these two modes of motion can only be imagined in connection with these organs. The motion of flying has been chosen as a symbol to represent that angels possess life, because it is the most perfect and most sublime movement of the brute creation. Men consider this motion a perfection to such an extent that they themselves wish to be able to fly, in order to escape easily what is injurious, and to obtain quickly what is useful, though it be at a distance. For this reason this motion has been attributed to the angels. There is besides another reason. The bird in its flight is sometimes visible, sometimes withdrawn from our sight; one moment near to us, and in the next far off; and these are exactly the circumstances which we must associate with the idea of angels, as will be explained below. This imaginary perfection, the motion of flight, being the exclusive property of the brute creation, has never been attributed to God. You must not be misled by the passage, “And he rode upon a cherub, and he did fly” (Ps. xviii. 10), for it is the cherub that did fly, and the simile only serves to denote the rapid arrival of that which is referred to in that passage. Comp.: “Behold, the Lord rideth upon a swift cloud, and shall come into Egypt” (Isa. xix. 1); that is, the punishment alluded to will come down quickly upon Egypt. Nor should expressions like “the face of an ox,” “the face of a lion,” “the face of an eagle,” “the sole of the foot of a calf,” found in the prophecies of Ezekiel (i. 10 and 7) mislead you; for all these are explained in a different manner, as you will learn later, and besides, the prophet only describes the animals (ḥayyot). The subject will be explained (III. i.), though by mere hints, as far as necessary, for directing your attention to the true interpretation. The motion of flying, frequently mentioned in the Bible, necessitates, according to our imagination, the existence of wings; wings are therefore given to the angels as symbols expressive of their existence, not of their true essence. You must also bear in mind that whenever a thing moves very quickly, it is said to fly, as that term implies great velocity of motion. Comp. “As the eagle flieth” (Deut. xxviii. 49). The eagle flies and moves with greater velocity than any other bird, and therefore it is introduced in this simile. Furthermore, the wings are the organs [lit. causes] of flight; hence the number of the wings of angels in the prophetic vision corresponds to the number of the causes which set a thing in motion, but this does not belong to the theme of this chapter.
