Job 38:9 - Matthew Poole's English Annotations on the Holy Bible

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. Thick darkness, i. e. black and dark clouds, called darkness by a 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 swaddling-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.
