disavows truth reads them, he will at first sight deride them, as being contrary to the real state of things. The cause of this is the circumstance, that our Sages spoke of these subjects in metaphors; they are too difficult for the common understanding of the people, as has been noticed by us several times. I will now return to the subject which I commenced to explain, in order to bring it to a conclusion. Our Sages commenced to adduce proofs from Scripture for their assertion that the things enumerated above are contained in the ʻarabot. As to justice and right they quote “Justice and judgment are the habitation of thy throne” (Ps. lxxxix. 18). In the same way they prove their assertion concerning all things enumerated by them, by showing that they are described as being related to God, as being near Him. Note this. In the Pirke Rabbi Eliezer it is said: God created seven rekiʻim (heavens), and out of all of them He selected the ʻaraboth for His royal throne; comp. “Exalt him who rideth upon the ʻarabot” (Ps. lxviii. 4). These are his (Rabbi Eliezer’s) words. Note them likewise. You must know that in Hebrew the collective noun denoting animals used for riding is “mercabah.” Instances of this noun are not rare. “And Joseph made ready his chariot” (merkabto) (Gen. xlvi. 29); “in the second chariot” (be-mirkebet) (ib. xli. 43); “Pharaoh’s chariots” (markebot) (Exod. xv. 4). The following passage especially proves that the Hebrew merkabah denotes a collection of animals: “And a merkabah came up and went out of Egypt for six hundred shekels of silver, and a horse for an hundred and fifty” (1 Kings x. 21). Hence we may learn that mercabah denotes here four horses. Therefore I think that when it was stated, according to the literal sense of the words, that four Ḥayyot (beasts) carry the Throne of Glory, our Sages called this “mercabah” on account of its similarity with the mercabah consisting of four single animals. So far has the theme of this chapter carried us, and we shall be compelled to make many further remarks on this subject. Here, however, it is our object, and the aim of all we have said, to show that “who rideth upon heaven” (Deut. xxxiii. 26) means “who sets the all-surrounding sphere in motion, and turns it by His power and will.” The same sense is contained in the conclusion of that verse: “and in his excellency the spheres,” i.e., who in His excellency moves the spheres (sheḥakim). In reference to the first sphere, the ʻarabot, the verb “to ride” is used, in reference to the rest, the noun “excellency,” because through the motion of the uppermost sphere in its daily circuit, all the spheres move, participating as parts in the motion of the whole; and this being that great power that sets everything in motion, it is called “excellency.” Let this subject constantly remain in your memory when you study what I am going to say; for it—i.e., the motion of the uppermost sphere—is the greatest proof
