Job 2:9 - The Popular Commentary by Paul E. Kretzmann

Then said his wife, whose trust in God was evidently not as strongly founded as that of the sufferer, unto him, Dost thou still retain thine integrity? He was clinging to a virtue which, as she supposed, availed him nothing at this time. The astonishment shown by Job's wife is that found in all unbelievers and false Christians when they cannot explain to their own satisfaction every act of God and every misfortune which befalls them. Curse God and die. She wanted him to renounce God, all his trust in Jehovah, and then give up the struggle for life or suffer the penalty of blasphemy.
