8:8-19 Bildad discourses well of hypocrites and evil-doers, and the fatal end 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. Bildad refers to the testimony of the ancients. Those teach best that utter 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, spun with great skill, but easily swept away, represents a man's pretensions to religion when without the grace of God in his heart. A formal 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 wicked 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.

15. he shall hold it fast—implying his eager grasp, when the storm of trial comes: as the spider "holds fast" by its web; but with this difference: the light spider is sustained by that on which it rests; the godless is not by the thin web on which he rests. The expression, "Hold fast," properly applies to the spider holding his web, but is transferred to the man. Hypocrisy, like the spider's web, is fine-spun, flimsy, and woven out of its own inventions, as the spider's web out of its own bowels. An Arab proverb says, "Time destroys the well-built house, as well as the spider's web."
