Genesis 9:2

The fear of you and the dread, etc. - Prior to the fall, man ruled the inferior animals by love and kindness, for then gentleness and docility were their principal characteristics. After the fall, untractableness, with savage ferocity, prevailed among almost all orders of the brute creation; enmity to man seems particularly to prevail; and had not God in his mercy impressed their minds with the fear and terror of man, so that some submit to his will while others flee from his residence, the human race would long ere this have been totally destroyed by the beasts of the field. Did the horse know his own strength, and the weakness of the miserable wretch who unmercifully rides, drives, whips, goads, and oppresses him, would he not with one stroke of his hoof destroy his tyrant possessor? But while God hides these things from him he impresses his mind with the fear of his owner, so that either by cheerful or sullen submission he is trained up for, and employed in, the most useful and important purposes; and even willingly submits, when tortured for the sport and amusement of his more brutish oppressor. Tigers, wolves, lions, and hyenas, the determinate foes of man, incapable of being tamed or domesticated, flee, through the principle of terror, from the dwelling of man, and thus he is providentially safe. Hence, by fear and by dread man rules every beast of the earth, every fowl of the air, and every fish of the sea. How wise and gracious is this order of the Divine providence! and with what thankfulness should it be considered by every human being!

9:2 He grants them power over the inferior creatures. He grants, 1. A title to them; into your hands they are delivered - For your use and benefit. 2. A dominion over them, without which the title would avail little; The fear of you and the dread of you shall be upon every beast - This revives a former grant, Genesis 1:28, only with this difference, that man in innocency ruled by love, fallen man rules by fear. And thus far we have still the benefit of it, 1. That those creatures which are any way useful to us are reclaimed, and we use them either for service or food, or both, as they are capable. 2. Those creatures that are any way hurtful to us are restrained; so that tho' now and then man may be hurt by some of them, yet they do not combine together to rise up in rebellion against man.
