Behold, as wild asses in the desert, go they forth to their work; rising betimes for a prey: the wilderness yieldeth food for them and for their children.

Who provideth for the raven his food? when his young ones cry unto God, they wander for lack of meat.

Surely the mountains bring him forth food, where all the beasts of the field play.
