1. Agmon, “hook,” is more correctly a rush-cord or rope made of reeds, (Gesenius;) and the question of the text suggests the wonderful strength of the leviathan by the impossibility of putting a rope around his nose, thus binding his jaws.
2. Choach, “thorn,” is really a ring; and the text probably refers to a custom, very ancient and still practiced, of inserting a strong iron ring into the jaw of a fish as soon as caught. A cord is fastened to the ring and the fish is let down into the water, where it remains until the fisherman has an opportunity of selling it.
