Ibn Ganaḥ (in his Book of Hebrew Roots) says that kenaf is used in the sense of “concealing,” in analogy with the Arabic kanaftu alshaian, “I have hidden something,” and accordingly explains, Isaiah xxx. 20, “And thy teacher will no longer be hidden or concealed.” It is a good explanation, and I think that kenaf has the same meaning in Deuteronomy xxiii. 1, “He shall not take away the cover (kenaf) of his father”; also in, “Spread, therefore, thy cover (kenafeka) over thine handmaid” (Ruth iii. 9). In this sense, I think, the word is figuratively applied to God and to angels (for angels are not corporeal, according to my opinion, as I shall explain). Ruth ii. 12 must therefore be translated “Under whose protection (kenafav) thou art come to trust”; and wherever the word occurs in reference to angels, it means concealment. You have surely noticed the words of Isaiah (Isa. vi. 2), “With twain he covered his face, and with twain he covered his feet.” Their meaning is this: The cause of his (the angel’s) existence is hidden and concealed; this is meant by the covering of the face. The things of which he (the angel) is the cause, and which are called “his feet” (as I stated in speaking of the homonym regel), are likewise concealed; for the actions of the intelligences are not seen, and their ways are, except after long study, not understood, on account of two reasons—the one of which is contained in their own properties, the other in ourselves; that is to say, because our perception is imperfect and the ideals are difficult to be fully comprehended. As regards the phrase “and with twain he flieth,” I shall explain in a special chapter (xlix.) why flight has been attributed to angels. CHAPTER XLIV The Hebrew ʻayin is a homonym, signifying “fountain”; e.g., “By a fountain (ʻen) of water” (Gen. xvi. 7). It next denotes “eye”; comp. (ʻayin) “Eye for eye” (Exod. xxi. 24). Another meaning of the word is “providence,” as it is said concerning Jeremiah, “Take him and direct thine attention (eneka) to him” (Jer. xxxix. 12). In this figurative sense it is to be understood when used in reference to God; e.g., “And my providence and my pleasure shall be there perpetually” (1 Kings ix. 3), as we have already explained (page 140); “The eyes (ʻene), i.e., the Providence of the Lord thy God, are always upon it” (Deut. xi. 12); “They are the eyes (ʻene) of the Lord, which run to and fro through the whole earth” (Zech. iv. 10), i.e., His providence is extended over everything that is on earth, as will be explained in the chapters in which we shall treat of Providence. When, however, the word “eye” is connected with the verb “to see,” (raah or ḥazah) as in “Open thine eyes, and see” (1 Kings xix. 16); “His eyes behold” (Ps. xi. 4), the phrase denotes perception of the mind, not that of the senses; for every sensation is a passive state, as is well known to you, and God is active, never passive, as will be explained by me.
