13. discover--rather, "uncover the surface" of his garment (skin,
Job 10:11):
strip off the hard outer coat with which the inner skin is
covered.
with--rather, "within his double jaws"; literally, "bridle"; hence
that into which the bridle is put, the double row of teeth; but
"bridle" is used to imply that none dare put his hand in to insert a
bridle where in other animals it is placed
(Job 41:4; 39:10).
