Matthew Poole and continuators on Job 3:1

1. AFter this [opened Job his Mouth, ] and [cursed his day. ]

He spake freely and boldly, as this Phrase is used Prov. 31. 8, 9. Eph. 6. 19. and elsewhere.

To wit, his Birth-day, as is evident from v. 3. which is called simply a Mans day, Hos. 7. 5. which also some others, through the same Infirmity, and in the same Circumstances, have cursed, as we see Ier. 20. 14. In vain do some men endeavour to excuse this and the following Speeches of Iob, who afterwards is reproved by God, and severely accuseth himself for them, Ch. 38. 2. and 40. 4. and 42. 3, 6. And yet he doth not proceed so far as to curse or blaspheme God, but makes the Devil a Lyar in his Prognosticks: But although he doth not break forth into direct and down right Reproaches of God, yet he makes secret and indirect Reflections upon Gods Providence. His Curse was sinful, both because it was vain, being applied to an unreasonable thing, which was not capable of blessing and cursing, and to a day that was past, and so out of the reach of all Curses; and because it was applied to one of Gods Creatures, all which were and are in themselves very good, and pronounced blessed by God, and so they are, if we do not turn them into Curses; and because it casts a blame upon God for bringing that day, and for giving him that Life which that day brought into the World. He pronounceth that day an unhappy, woful, and cursed day, not in it self, but with respect to himself.
