John Trapp on Job 9:21

Verſe 21. Though I were perfect] That is, of an unblameable converſation, yet could not I know mine own ſoul, that is, thoſe ſecret ſins Pſalm 19.12. thoſe litters of luſts that lurk therein, therefore I despiſe my life, I have no joy at all of it, but could wiſh to be out of the world, to be rid of theſe evil inmates, that will not out of doors till the houſe fall upon the heads of them, till the earthly Tabernacle that harboureth them be once diſſolved. Others read and ſenſe the words thus, I am perfect or upright, neither do I know mine own ſoul, i. e. quicquam perverſi in anima mea, any allowed ſin in my ſoul; yet I am ſo afflicted, that I deſpiſe my life, as being but a continued death. Aben-Ezra reads the verſe with an admiration, thus, Perfect I am; and think you that I know not mine own ſoul▪ that I am ſo great a ſtranger to my ſelf! or, that I have ſo little care of mine own good, as that I deſpiſe my life, and walk at all adventures! Tremellius thus, I am upright, whatever you my friends would make of me, neither value I my life or ſoul in compariſon of mine integrity: my life is but a trifle to my conſcience &c.
