John Trapp on Job 29:6

Verſe 6 When I waſhed my ſteps with butter] When I had of every thing Gods plenty, as they can it. Butter enough to have waſhed my feet in, had I been ſo proud and profuſe. And Oyle great ſtore, inſomuch as that Rivers thereof ſeemed to flow for me from thoſe Rocks and craggy Mountaines in Arabia Petraea, where ſome ſay Job dwelt. Lavater upon the Text, tells us of Rocks that yeeld Oyle, and of Petrolium or Petrelaeum, a Soveraign Oyntment (very good againſt diverſe Diſeaſes) that iſſueth out of Rocks, whence alſo it hath its name (not unlike that berry which the French call, Ʋva de Spine, the Grape of a thorn:) But this whole verſe ſeemeth to be an Hyperbole, (not unlike that of Zophar, chap. 20.17. and that of Moſes, Deut. 32.13. Confer Gen. 49.11. and Pſal. 80.16.) importing the very great abundance of all outward comforts and contentments, that Job once enjoyed. He had the reward of humility, and the fear of the Lord, even Riches, and Honour, and Life, Prov. 22.4.Dec. D. l. 5. c. 25 Riches he had quantas optare nullus auderet, (as Auſtin ſaith of Conſtantine the Great) more then heart could wiſh. What Honour he had with his Wealth, (and that is to be choſen before Riches, Proverbs 22.1.) he ſetteth forth at large in the following verſes. And what long life he promiſed himſelfe, not without the continuance of both the former, ſee verſe 18, 19, 20, with chap. 42.12, 16, 17.
