John Trapp on Job 8:15

Verſe 15. He ſhall lean upon his houſe] The ſpider ſhall; ſo Vatablus taketh it: but better, the hypocrite leaneth, or layeth his whole weight upon his houſe, that is, wealth, children, friends, clients, tenants &c. as did Doeg, P[illegible: 1 letter]al. 52.7. Haman, Eſth. 4.11. That profane Earl of Weſtmorland, who ſaid, that he needed not at all to pray to God; for he had tenants enow to pray for him. Bildad probably glanceth here at Job, as if he had once truſted in his riches, relations &c. which yet Job diſavoweth, chap. 31.

But it ſhall not ſtand] No more then the ſpiders houſe doth, born down ſometimes by her very waight, and not only by the wind. Hypocrites ruine their own houſes by their ſins, and particularly by relying on them. Though thou build thy palace as high as heaven, ſaid the Oracle to Phocas, yet ſin that lieth at the bottom will be the ruine of it.

He ſhall hold it faſt] Mordicùs tenebit, he ſhall hold it, not with his hands only, but with his teeth alſo, as Cynegiras did the Perſian ſhip, or as a drowning man doth the branch of a tree.

But it ſhall noe endure] All will not do; riches avail not in the day of wrath &c. An hypocrite runs in his trouble to former falſe refuges; he truſted to his legs, or repairs to his buſhes, as the hunted hare doth to the places that ſhe uſed when ſhe lived at quiet, thither ſhe flies when ſhe knows not how elſe to eſcape; but all to no purpoſe.
