Job 39:30

Her young ones also suck up blood,.... As well as herself, being brought up to it by her. The eagle cares not for water, but drinks the blood of her prey; and so her young ones after her, as naturalists report w. And Aelianus says x the same of the hawk, that it eats no seeds, but devours flesh and drinks blood, and nourishes her young ones with the same.

And where the slain are, there is she; where there has been a battle, and carcasses left on the field, the eagles will gather to them. This is particularly true of that kind of eagles called vulture eagles, as Aristotle y and Pliny z observe; see Matthew 24:28. Now since Job was so ignorant of the nature of these creatures, and incapable of governing and directing them; and what they had of any excellency were of God, and not of him, nor of any man; how unfit must he be to dispute with God, and contend with him about his works of providence? which to convince him of was the design of this discourse about the creatures; and which had its intended effect, as appears in the next chapter.
