From there he spies out food; his eyes see it from afar.
The birds of the air are proofs of the wonderful power and providences of God, as well as the beasts of the earth; God here refers particularly to two stately ones: - 1. The hawk, a noble bird of great strength and sagacity, and yet a bird of prey, Job 39:26.
Commenting on Job 39:26-30
From thence she seeketh the prey,.... From the high rock; from whence she can look down into valleys, and even into the sea; and spy what is for her purpose, and descend and seize upon them; as lambs, fawns, geese, shellfish, &c. though they may lie in the most hidden and secret places.
seeketh--is on the lookout for. behold--The eagle descries its prey at an astonishing distance, by sight, rather than smell.
