15. The statement as such is general: every moving thing that moveth upon the earth. There are some who believe that men at the time of Noah made no distinction between clean and unclean animals as regards food. But I hold a different opinion. For since such difference had been established before that time and was carefully observed in the Law afterward, I believe that men used only clean beasts for food; that is, such as were offered in sacrifice. Hence the general declaration must be understood with a modification: Everything that liveth and moveth, of clean beasts, is to be food for you. For, in general, human nature loathes serpents, wolves, ravens, mice, and dormice, though certain tribes may be found who relish even these animals. The fear and terror of man is upon all beasts of the earth, because he is allowed to kill them; but it does not follow that man uses them all for food. It is probable that Noah ate clean beasts only; and only clean beasts, he knew, were acceptable to Jehovah in sacrifice. 16. But there is another thing hard to understand. How can it be that the terror and fear of man is upon all animals when wolves, lions, bears, wild boars, and tigers devour men, and are rather a terror to men? So with the entire family of serpents, from which we flee at a glance. What shall we say here? Is the Word of God untruthful? I answer: Though we, being aware of our danger, flee from such beasts and are afraid of them, yet they, likewise, fear man. Even the fiercest beasts become terrified and flee at the first sight of man; but when they become enraged they overcome man by reason of their bodily strength. 17. But, you say, why do they fear when they are stronger? I answer: They know that man is endowed with reason, which is more powerful than any beast. The skill of man masters even elephants, lions, and tigers. Whatever man's bodily strength is unable to do, that he accomplishes by his skill and his reasoning powers. How would it otherwise be possible for a boy of ten years to control an entire herd of cattle? Or for man to guide a horse, an animal of singular fierceness and strength, to go in whatever direction he desires, now urging it forward and then compelling it to a more moderate gait? All these things are done by man's skill, not by his strength. Hence, we do not lack clear proofs that the fear of man remains upon the beasts, which harm man when they become enraged, and for that reason are feared by him.
