He maketh the deep to boil like a pot,.... Which is all in a from through the violent agitation and motion of the waves, caused by its tossing and tumbling about; which better suits with the whale than the crocodile, whose motion in the water is not so vehement;he maketh the sea like a pot of ointment; this also seems to make against the crocodile, which is a river fish, and is chiefly in the Nile.
Lakes indeed are sometimes called seas, in which crocodiles are found; yea, they are also said to be in the seas, Eze 32:2; and Pliny speaks of them as common to the land, river, and sea; and the Nile is in the Alcoran called the sea, and its ancient name was "Oceames" with the Egyptians, that is, in Greek, "ocean", as Diodorus Siculus affirms; and so it is thought to be the Egyptian sea in Isa 11:15.
It is observed that they leave a sweet scent behind them; thus Peter Martyr , in his account of the voyages of Columbus in the West Indies, says, they sometimes met with crocodiles, which, when they fled or took water, they left a very sweet savour behind them, sweeter than musk or castoreum.
But this does not come up to the expression here of making the sea like a pot of ointment; but the sperm of the whale comes much nearer to it, which is of a fat oily nature, and like ointment, and which the whale sometimes throws out in great abundance, so that the sea is covered with it; whole pails full may be taken out of the water; it swims upon the sea like fat; abundance of it is seen in calm weather, so that it makes the sea all foul and slimy : and there are a sort of birds called "mallemuck", which fly in great numbers and feed upon it .
I cannot but remark what the bishop of Bergen observes of the sea serpent, that its excrements float on the water in summertime like fat slime. "Fervetque----aequor". Virgil. Georgic. l. 1. v. 327. Nat.
