Jamieson, Fausset and Brown on Job 4:10-11

10-11. lion--that is, wicked men, upon whom Eliphaz wished to show that calamities come in spite of their various resources, just as destruction comes on the lion in spite of his strength (Psa 58:6; 2Ti 4:17). Five different Hebrew terms here occur for "lion." The raging of the lion (the tearer), and the roaring of the bellowing lion and the teeth of the young lions, not whelps, but grown up enough to hunt for prey. The strong lion, the whelps of the lioness (not the stout lion, as in English Version) [Barnes and Umbreit]. The various phases of wickedness are expressed by this variety of terms: obliquely, Job, his wife, and children, may be hinted at by the lion, lioness, and whelps. The one verb, "are broken," does not suit both subjects; therefore, supply "the roaring of the bellowing lion is silenced." The strong lion dies of want at last, and the whelps, torn from the mother, are scattered, and the race becomes extinct.
