Earlier in the book Job had hesitated to confront God ( Job 9:14). Gradually he became more confident and demanded an audience with God ( Job 13:22 a). Still later, he spoke almost as God"s equal, boasting that he would approach God as a prince ( Job 31:37). Now, having discovered his own "insignificance" ( Job 40:4), he had nothing more to say to God ( Job 40:5). God had humbled him. Job felt no need to speak more since he had repeated himself earlier ( Job 40:5; cf. Job 33:14). However, Job did not confess any sin. Therefore God proceeded to speak again. Hebrews , not Job , found it necessary to speak "even twice" ( Job 40:5). [source][source][source]
