John Trapp on Job 11:4

Verſ. 4. For thou haſt ſaid.] Thou haſt confidently affirmed; and this he makes to be a loud lie, and not an idle word only. But where and when had Job ſaid it? Did not Zophar openly play the Sophiſter, ſo interpreting what Job had ſpoken chap. 6.10. and 9.22. and 10.7. in defence of his innocency, as if Job had maintained that he was free from all ſin; whereas notwithſtanding, he had very often witneſſed and confeſſed himſelf to be a ſinner, inſomuch, as that albeit he were without ſin, yet he could not be accounted clear and pure in the ſight of God? But Zophar took theſe for good words only, and was therfore ſo ſharp-ſet againſt him. So Cyril and Theodoret miſtook one another, and objected hereſie mutually: when as afterwards it appeared, that they were both of one judgment. Charity would have taught Zophar to have taken Job in a better ſenſe, and to have ſaid of him as Cruciger did of Luther, eum commodiùs ſentire quàm loquitur, dum efferveſcit, that he held right, though in his heat he ſpake not ſo fitly as might be wiſhed; good mens words are reverenter gloſſanda (as one ſaid of the Lawes) to have a reverent gloſſe put upon them, and not by a ſpiritual unmannerlineſſe, to be taken with the left hand; when they might and ought to be taken with the right.

My doctrine is pure] Clear as chryſtal, tranſparent as a chryſtal glaſſe with a light in the midſt; you may ſee through it, and find no flaw or filth in it: Job was no profeſſed preacher, yet he had not concealed the words of the Holy One, chap. 6.10. As he had received the knowledg of the truth from parents and teachers (the word here rendred doctrine, comes from a root that ſignifieth to receive) ſo he had freely and purely imparted it to others, commending it unto them as ſound and ſincere, and therefore well worthy of all acceptation. But that which troubled Zophar and his two fellows was, that Job ſhould affirm that God did afflict good men in this world as heavily as bad men, which yet was an irrefragable truth, ſuch as Job reſolved to live and die in.

And I am clean in thine eyes] i. e. I am not ſinleſſe, but ſincere and upright, no hypocrite (as you have charged me) no worker of iniquity, but one that would be cleanſed from all filthineſſe of fleſh and ſpirit, and do by the daily practice of mortification, purifie my ſelf as God is pure: more then this Job ſaid not, though Zophar thought he did, and therefore wiſheth in the next words that God himſelf would convince him of his errour.
