Who can open the doors of his face? - His mouth. The same term is sti 1 used to denote the mouth - from its resemblance to a door. The idea is, that no one would dare to force open his mouth. This agrees better with the crocodile than almost any other animal. It would not apply to the whale. The crocodile is armed with a more formidable set of teeth than almost any other animal; see the description in the notes at Job 41:1. Bochart says that it has sixty teeth, and those much larger than in proportion to the size of the body. Some of them, he says, stand out; some of them are serrated, or like a saw, fitting into each other when the mouth is closed; and some come together in the manner of a comb, so that the grasp of the animal is very tenacious and fearful; see a full description in Bochart.

The doors of his face? - His jaws which are most tremendous.

Who can (f) open the doors of his face? his teeth [are] terrible round about.
(f) Who dare look in his mouth?

Who can open the doors of his face?.... Of his mouth, the jaws thereof, which are like a pair of folding doors: the jaws of a crocodile have a prodigious opening. Peter Martyr (u) speaks of one, whose jaws opened seven feet broad; and Leo Africanus (w) affirms he saw some, whose jaws, when opened, would hold a whole cow. To the wideness of the jaws of this creature Martial (x) alludes; and that the doors or jaws of the mouth of the whale are of a vast extent will be easily believed by those who suppose that was the fish which swallowed Jonah;
his teeth are terrible round about; this may seem to make against the whale, the common whale having none; though the "ceti dentati" are a sort of whales that have many teeth in the lower jaw, white, large, solid, and terrible (y). Olaus Magnus (z) speaks of some that have jaws twelve or fourteen feet long; and teeth of six, eight, and twelve feet; and there is a sort called "trumpo", having teeth resembling those of a mill (a). In the spermaceti whale are rows of fine ivory teeth in each jaw, about five or six inches long (b). But of the crocodile there is no doubt; which has two rows of teeth, very sharp and terrible, and to the number of sixty (c).

doors of . . . face--his mouth. His teeth are sixty in number, larger in proportion than his body, some standing out, some serrated, fitting into each other like a comb [BOCHART].

Doors - His mouth. If it be open, none dare enter within, and if it be shut, none dare open it.
