Job 38:39

Wilt thou hunt the prey for the lion? -The appeal here is to the instincts with which God has endowed animals, and to the fact that he had so made them that they would secure their own food. He asks Job whether he would undertake to do what the lion did by instinct in finding his food, and by his power and skill in seizing his prey. There was a wise adaptation of the lion for this purpose which man could neither originate nor explain. Or fill the appetite of the young lions -Margin, as in Hebrew “life.” The word life is used here for hunger, as the appetite is necessarily connected with the preservation of life.
