Matthew Poole and continuators on Job 41:13

13. Who can discover the face of his garment ? or who can come to him with his double bridle ?

Or, uncover, or take off from him.

The upper or outward part of his garment, or, the garment it self. the word face being oft redundant, as Gen. 1. 2. & 23. 3. and oft elsewhere. And by the garment is meant the skin, which covers the whole Body, and may be taken off from the Body like a garment. Who dare attempt to touch his very outward skin? much less dare any venture to approach to him, to give him a deep or deadly wound.

To put it into his mouth and lead him by it to thy Stable and Service, as thou dost by an Horse. Or rather, (because he plainly seems to persist in describing the several parts of his Body: of which he speaks both in the foregoing and following words) Who can come within his double Bridle, to wit, his vast Jaws, which have some resemblance to a double Bridle: whence the Greeks call those parts of the face which reach to the Jaws on both sides, the Bridles.

Marginal references: Or, within.
