SEV Biblia, Chapter 8:15
El se apoyará sobre su casa, pero no permanecerá en pie; se asirá a ella, más no se afirmará.
Clarke's Bible Commentary - Job 8:15
Verse 15. He shall lean upon his house ] This is all allusion to the spider. When he suspects his web, here called his house, to be frail or unsure, he leans upon it in different parts, propping himself on his hinder legs, and pulling with his fore claws, to see if all be safe. If he find any part of it injured, he immediately adds new cordage to that part, and attaches it strongly to the wall. When he finds all safe and strong, he retires into his hole at one corner, supposing himself to be in a state of complete security, when in a moment the brush or the besom sweeps away both himself, his house, and his confidence. This I have several times observed; and it is in this that the strength and point of the comparison consist. The wicked, whose hope is in his temporal possessions strengthens and keeps his house in repair; and thus leans on his earthly supports; in a moment, as in the case of the spider, his house is overwhelmed by the blast of God's judgments, and himself probably buried in its ruins. This is a very fine and expressive metaphor, which not one of the commentators that I have seen has ever discovered.
Matthew Henry Commentary
Verses 8-19 - Bildad discourses well of hypocrites and evil-doers, and the fatal en of all their hopes and joys. He proves this truth of the destruction of the hopes and joys of hypocrites, by an appeal to former times. Bilda refers to the testimony of the ancients. Those teach best that utte words out of their heart, that speak from an experience of spiritual and divine things. A rush growing in fenny ground, looking very green but withering in dry weather, represents the hypocrite's profession which is maintained only in times of prosperity. The spider's web, spu with great skill, but easily swept away, represents a man's pretension to religion when without the grace of God in his heart. A forma professor flatters himself in his own eyes, doubts not of his salvation, is secure, and cheats the world with his vain confidences The flourishing of the tree, planted in the garden, striking root to the rock, yet after a time cut down and thrown aside, represents wicke men, when most firmly established, suddenly thrown down and forgotten This doctrine of the vanity of a hypocrite's confidence, or the prosperity of a wicked man, is sound; but it was not applicable to the case of Job, if confined to the present world.
