Even such phrases as, "They saw the God of Israel" (Exod. 24, 10), "He saw the form of Jhvh" (Num. 12, 8), the Rabbinic expression "Maase Merkaba" (work of the divine chariot, _cf._ above, p. xvi), and the later discussions concerning the "Measure of the divine stature" (Shiʿur Komah), must not be rejected. These visual images representative of God are calculated to inspire fear in the human soul, which the bare conception of the One, Omnipotent, and so on, cannot produce.[196] As Judah Halevi is unwilling to yield to the philosophers and explain away the supernaturalism of prophecy, maintaining rather on the contrary that the supernatural character of the prophetic vision is an evidence of the superior nature of Israel as well as of their land and their language, so he insists on the inherent value of the ceremonial law, including sacrifices. To Saadia, and especially to Bahya and Maimonides, the test of value is rationality. The important laws of the Bible are those known as the rational commandments. The other class, the so-called traditional commandments, would also turn out to be rational if we knew the reason why they were commanded. And in default of exact knowledge it is the business of the philosopher to suggest reasons. Bahya lays the greatest stress upon the commandments of the heart, _i. e._, upon the purity of motive and intention, upon those laws which concern feeling and belief rather than outward practice. Judah Halevi's attitude is different. If the only thing of importance in religion were intention and motive and moral sense, why should Christianity and Islam fight to the death, shedding untold human blood in defence of their religion. As far as ethical theory and practice are concerned there is no difference between them. Ceremonial practice is the only thing that separates them. And the king of the Chazars was told repeatedly in his dreams that his intentions were good but not his practice, his religious practice. To be sure the ethical law is important in any religion, but it is not peculiar to religion as such. It is a necessary condition of social life, without which no association is possible, not even that of a robber band. There is honesty even among thieves. Religion has its peculiar practices, and it is not sufficient for an Israelite to observe the rational commandments alone. When the Prophets inveigh against sacrifices; when Micah says (6, 8), "He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God," they mean that the ceremonies alone are not sufficient; but surely a man is not fully an Israelite if he neglects the ceremonial laws and observes only the rational commandments. We may not understand the value of the ceremonial laws, the meaning of the institution of sacrifices. But neither do we understand why the rational soul does not attach itself to a body except
