Job 8:15

“He shall lean upon his house, etc.] Either the spider or the hypocrite, or the hypocrite as the spider; that is, that which is the ground of his confidence, which is as the spider’s house, on that he shall depend, either on his riches and outward prosperity, which he promises himself a long continuance of, and from whence he concludes himself to be high in the favour and good will of God; or on his works of righteousness, his outward profession of religion, attendance on external worship, and a round of duties performed by him; in these he trusts, on these he depends, in such webs he enwraps himself, in such a house he dwells, and imagines himself safe; which is only making flesh his arm,…”

“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."”

“He shall lean upon his house - This is an allusion to the web or house of the spider. The hope of the hypocrite is called the house which he has built for himself; his home, his refuge, his support. But it shall fail him. In times of trial he will trust to it for support, and it will be found to be as frail as the web of the spider. How little the light and slender thread which a spider spins would avail a man for support in time of danger! So frail and unsubstantial will be the hope of the hypocrite! It is impossible to conceive any figure which would more strongly describe the utter vanity of the hopes of the wicked. A similar comparison occurs in the Koran, Sur. 28, 40: “They who assume…”

“House - He shall trust to the multitude of his children and servants, and to his wealth, all which come under the name of a man's house in scripture. Hold it - To uphold himself by it. But his web, that refuge of lies, will be swept away, and he crushed in it. Job 8:16”

“it shall not stand: Job 18:14, Job 27:18; Psa 52:5-7, Psa 112:10; Pro 10:28; Mat 7:24-27; Luk 6:47-49 Job 8:16”
