John Trapp on Job 15:29

Verſe 29. he ſhall not be rich, neither ſhall his ſubſtance, &c.] If he be rich, it is for a miſchief, neither is it likely long to continue with him, for God will blow upon, and blaſt his ſubſtance, which is the fort and ſtrength, Iſai. 10.14. He reſolvs he will be rich, 1 Tim. 6.9. and is ſet upon it: God to croſſe him, ſaith here, He ſhall not be rich, but I will make a poor fool of him, according to that. Jer. 17.11. As the Partridge ſitteth on eggs and hatcheth them not; ſo he that getteth riches and not by right, ſhall leave them in the midſt of his dayes, and at his end ſhall be a fool. There is a curſe upon unlawful practiſes, though men be induſtrious, as in Jehoiachim; Jer. 22. it is God that giveth power to get wealth, Deut. 8.18. Our care can no more add a penny to our eſtate, then it can a cubit to our ſtature, Mat. 6.27.

He ſhall not prolong the perfection thereof.] Vulgar, He ſhall not ſend forth his root in the earth, A man ſhall not be eſtabliſhed by wickedneſſe (ſaith Solomon) but the root of the righteous ſhall continue. Prov. 12.3. See the Note there.
