John Trapp on Job 18:13

Verſe 13. It ſhall devour the ſtrength of his skin] i.e. his bones which ſupport his skin; theſe deſtruction ſhall devour or ſwallow up at a bit, as an hungry Monſter.

The firſt born of death ſhall devour his ſtrength] i.e. The Devil. ſay ſome, that Deſtroyer, Rev. 9.11. that old Man-ſlayer, John 8.44. Prince of death, Heb. 2.14 (as Chriſt is called Prince of Life, Act. 3.15) and firſt born of death, as Chriſt is the firſt born of the Reſurrection, Col. 1.18. Others underſtand it, De cruentiſſima at funeſtiſſima morte, of the moſt tragick and cruel kind of death. See Iſai. 14.30. Broughton readeth it, A ſtrange death ſhall cat the branches of his body, judgments ſhal come upon thee in their perfection, ſaith God to Babylon, Iſai. 47.9.
