According to the understanding of Noah it was revealed to him that God was about to destroy the whole human race, for Noah thought that beyond the limits of Palestine the world was not inhabited.
Not only in matters of this kind, but in others more important, the prophets could be, and in fact were, ignorant; for they taught nothing special about the Divine attributes, but held quite ordinary notions about God, and to these notions their revelations were adapted, as I will demonstrate by ample Scriptural testimony; from all which one may easily see that they were praised and commended, not so much for the sublimity and eminence of their intellect as for their piety and faithfulness.
Adam, the first man to whom God was revealed, did not know that He is omnipotent and omniscient; for he hid himself from Him, and attempted to make excuses for his fault before God, as though he had had to do with a man; therefore to him also was God revealed according to his understanding—that is, as being unaware of his situation or his sin, for Adam heard, or seemed to hear, the Lord walking in the garden, calling him and asking him where he was; and then, on seeing his shamefacedness, asking him whether he had eaten of the forbidden fruit. Adam evidently only knew the Deity as the Creator of all things. To Cain also God was revealed, according to his understanding, as ignorant of human affairs, nor was a higher conception of the Deity required for repentance of his sin.
To Laban the Lord revealed Himself as the God of Abraham, because Laban believed that each nation had its own special divinity (see Gen. xxxi. 29). Abraham also knew not that God is omnipresent, and has foreknowledge of all things; for when he heard the sentence against the inhabitants of Sodom, he prayed that the Lord should not execute it till He had ascertained whether they all merited such punishment; for he said (see Gen. xviii. 24), "Peradventure there be fifty righteous within the city," and in accordance with this belief God was revealed to him; as Abraham imagined, He spake thus: "I will go down now, and see whether they have done altogether according to the cry of it which is come unto Me; and if not I will know." Further, the Divine testimony concerning Abraham asserts nothing but that he was obedient, and that he "commanded his household after him that they should keep the way of the Lord" (Gen. xviii. 19); it does not state that he held sublime conceptions of the Deity.
Moses, also, was not sufficiently aware that God is omniscient, and directs human actions by His sole decree, for although God himself says that the Israelites should hearken to Him, Moses still considered the matter doubtful and repeated, "But if they will not believe me, nor hearken unto my voice." To him in like manner God was revealed as taking no part in, and as being ignorant of, future human actions: the Lord gave him two signs and said, "And it shall come to pass that if they will not believe thee, neither hearken to the voice of the first sign, that they will believe the voice of the latter sign; but if not, thou shalt take of the water of the river," etc. Indeed, if any one considers without prejudice the recorded opinions of Moses, he will plainly see that Moses conceived the Deity as a Being Who has always existed, does exist, and always will exist, and for this cause he calls Him by the name Jehovah, which in Hebrew signifies these three phases of existence: as to His nature, Moses only taught that He is merciful, gracious, and exceeding jealous, as appears from many passages in the Pentateuch. Lastly, he believed and taught that this Being was so different from all other beings, that He could not be expressed by the image of any visible thing; also, that He could not be looked upon, and that not so much from inherent impossibility as from human infirmity; further, that by reason of His power He was without equal and unique. Moses admitted, indeed, that there were beings (doubtless by the plan and command of the Lord) who acted as God's vicegerents—that is, beings to whom God had given the right, authority, and power to direct nations, and to provide and care for them; but he taught that this Being Whom they were bound to obey was the highest and Supreme God, (or to use the Hebrew phrase) God of gods, and thus in the song (Exod. xv. 11) he exclaims, "Who is like unto Thee, O Lord, among the gods?" and Jethro says (Exod. xviii. 11), "Now I know that the Lord is greater than all gods." That is to say, "I am at length compelled to admit to Moses that Jehovah is greater than all gods, and that His power is unrivalled." We must remain in doubt whether Moses thought that these beings who acted as God's vicegerents were created by Him, for he has stated nothing, so far as we know, about their creation and origin. He further taught that this Being had brought the visible world into order from Chaos, and had given Nature her germs, and therefore that He possesses supreme right and power over all things; further, that by reason of this supreme right and power He had chosen for Himself alone the Hebrew nation and a certain strip of territory, and had handed over to the care of other gods substituted by Himself the rest of the nations and territories, and that therefore He was called the God of Israel and the God of Jerusalem, whereas the other gods were called the gods of the Gentiles. For this reason the Jews believed that the strip of territory which God had chosen for Himself, demanded a Divine worship quite apart and different from the worship which obtained elsewhere, and that the Lord would not suffer the worship of other gods adapted to other countries. Thus they thought that the people whom the king of Assyria had brought into Judæa were torn in pieces by lions because they knew not the worship of the National Divinity (2 Kings xvii. 25)....
If we now examine the revelations to Moses, we shall find that they were accommodated to these opinions; as he believed that the Divine Nature was subject to the conditions of mercy, graciousness, etc., so God was revealed to him in accordance with his idea and under these attributes (see Exodus xxxiv. 6, 7, and the second commandment). Further it is related (Ex. xxxiii. 18) that Moses asked of God that he might behold Him, but as Moses (as we have said) had formed no mental image of God, and God (as I have shown) only revealed Himself to the prophets in accordance with the disposition of their imagination, He did not reveal Himself in any form. This, I repeat, was because the imagination of Moses was unsuitable, for other prophets bear witness that they saw the Lord; for instance, Isaiah, Ezekiel, Daniel, etc. For this reason God answered Moses, "Thou canst not see My face;" and inasmuch as Moses believed that God can be looked upon—that is, that no contradiction of the Divine nature is therein involved (for otherwise he would never have preferred his request)—it is added, "For no one shall look on Me and live," thus giving a reason in accordance with Moses' idea, for it is not stated that a contradiction of the Divine nature would be involved, as was really the case, but that the thing would not come to pass because of human infirmity....
Lastly, as Moses believed that God dwelt in the heavens, God was revealed to him as coming down from heaven on to a mountain, and in order to talk with the Lord Moses went up the mountain, which he certainly need not have done if he could have conceived of God as omnipresent.
The Israelites knew scarcely anything of God, although He was revealed to them; and this is abundantly evident from their transferring, a few days afterwards, the honor and worship due to Him to a calf, which they believed to be the god who had brought them out of Egypt. In truth, it is hardly likely that men accustomed to the superstitions of Egypt, uncultivated and sunk in most abject slavery, should have held any sound notions about the Deity, or that Moses should have taught them anything beyond a rule of right living; inculcating it not like a philosopher, as the result of freedom, but like a lawgiver compelling them to be moral by legal authority. Thus the rule of right living, the worship and love of God, was to them rather a bondage than the true liberty, the gift and grace of the Deity. Moses bid them love God and keep His law, because they had in the past received benefits from Him (such as the deliverance from slavery in Egypt), and further terrified them with threats if they transgressed His commands, holding out many promises of good if they should observe them; thus treating them as parents treat irrational children. It is, therefore, certain that they knew not the excellence of virtue and the true happiness.
Jonah thought that he was fleeing from the sight of God, which seems to show that he too held that God had entrusted the care of the nations outside Judæa to other substituted powers. No one in the whole of the Old Testament speaks more rationally of God than Solomon, who in fact surpassed all the men of his time in natural ability. Yet he considered himself above the law (esteeming it only to have been given for men without reasonable and intellectual grounds for their actions), and made small account of the laws concerning kings, which are mainly three: nay, he openly violated them (in this he did wrong, and acted in a manner unworthy of a philosopher, by indulging in sensual pleasure), and taught that all Fortune's favors to mankind are vanity, that humanity has no nobler gift than wisdom, and no greater punishment than folly. (See Proverbs xvi. 22, 23.)
... God adapted revelations to the understanding and opinions of the prophets, and ... in matters of theory without bearing on charity or morality, the prophets could be, and, in fact, were ignorant, and held conflicting opinions. It therefore follows that we must by no means go to the prophets for knowledge, either of natural or of spiritual phenomena.
