Yahweh has risen like a lion from His covert, and at His roaring the whole world is filled with terror and confusion.
Upon his habitation - Against His pasture; i. e., Judaea. Yahweh comes forth as the lion to destroy the sheep which lie terrified within the circle of the tents.
A shout - The vintage-shout, here used for the war-cry. Compare Isaiah 16:9; Isaiah 63:3.
