Matthew Poole and continuators on Job 38:9

9. When I made the cloud the garment thereof , and thick darkness a swadling band for it :

When I covered it with Vapours and Clouds which arise out of the Sea, and by God's appointment hover above it and cover it like a garment.

i. e. Black and dark Clouds, called Darkness by an usual Metonymy of the Adjunct. So the same thing is repeated in other words after the manner.

Having compared the Sea to a New-born Infant he continues in the same Metaphor, and makes the Clouds as swadling-bands to keep the Sea within its bounds: though indeed neither Clouds, nor Air, nor Sands, and shores, can bound the Sea, but it is God alone who doth it in and with these things.
