Praise the LORD from the earth, ye dragons, and all deeps: Praise the Lord from the earth - As in the first address, he calls upon the heavens and all that belong to them; so here, in this second part, he calls upon the earth, and all that belong to it.
Ye dragons - תנינים tanninim, whales, porpoises, sharks, and sea-monsters of all kinds.
And all deeps - Whatsoever is contained in the sea, whirlpools, eddies, ground tides, with the astonishing flux and reflux of the ocean.
Every thing, in its place and nature, shows forth the perfections of its Creator.
