Jamieson, Fausset and Brown on Job 35:15

15. As it is, because Job waited not trustingly and patiently (Job 35:14; Nu 20:12; Zep 3:2; Mi 7:9), God hath visited ... ; yet still he has not taken (severe) cognizance of the great multitude (English Version wrongly, "extremity") of sins; therefore Job should not complain of being punished with undue severity (Job 7:20; 11:6). Maurer translates: "Because His anger hath not visited (hath not immediately punished Job for his impious complaints), nor has He taken strict (great) cognizance of his folly (sinful speeches); therefore," &c. For "folly," Umbreit translates with the Rabbins, "multitude." Gesenius reads with the Septuagint and Vulgate needlessly, "transgression."
