On the rock he dwells and makes his home, on the rocky crag and stronghold.
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
She dwelleth and abideth on the rock, upon the crag of the rock, and the strong place. Where she and her young are safe: so Pliny (r) says, eagles make their nests in rocks, even in the precipices of them, as the philosopher quoted in the preceding verse; and here on the tooth, edge, or precipice of the rock, which is inaccessible, and so like a strong fortified place.
abideth--securely (Psa 91:1); it occupies the same abode mostly for life. crag--literally, "tooth" (Sa1 14:5, Margin). strong place--citadel, fastness.
