New Defender's Study Bible Notes
7:3 months of vanity. Evidently Job had already been suffering for “months” before the arrival of the three friends.
7:12 a whale. This “whale” (Hebrew tannin, same as in Genesis 1:21) was actually some kind of great sea monster—a sea serpent or marine dinosaur. The word tannin is usually translated “dragon.”
7:14 scarest me with dreams. Eliphaz had thought to impress Job with his account of the visit and message he had received from a spirit (Job 4:12-21). However, Job easily discerned that this spirit could not have been sent from God; rather, the spirit intended merely to frighten him into blaspheming against the God he trusted.
7:17 What is man. At this point, Job directs his comments in prayer to God, rather than in defense to Eliphaz. In a sense, he raises the question which David would ask many centuries later (Psalm 8:4).
7:20 I have sinned. Job frankly confesses that he, like all men, is a sinner, even though he is unaware of any specific sin that might have led God to punish him so severely, as contended by his friends.
7:21 pardon my transgression. Job knew he had confessed such sin as he knew, and had offered the appropriate sacrifices (Job 1:5), so he could not understand why God seemed to be refusing His promised forgiveness.
