Job 2:9

The devil spared his wife with cruel intent to be the instrument of his temptations, and the aggravation of Job's misery, by unnatural unkindness to him, which is declared Job 19:17, and elsewhere. Dost thou still retain thine integrity? art thou yet so weak to persist in the practice of piety, when it is not only unprofitable to thee, but the chief occasion of all these thy insupportable miseries, and when God himself not only forsakes and leaves thee in this helpless and hopeless condition, but is turned to be thy greatest enemy? Curse God, and die; seeing thy blessing of God availeth thee so little, it is time to change thy note, Curse God, and die, i.e. reproach him to his face, and tell him of his injustice and unkindness to thee, and that he loves his enemies, and hates his friends; and that will provoke him to take away thy life, and so end thy torments. Or, Curse God, though though die for it. But although this word sometimes signifies cursing, as Job 1:11 1 Kings 21:10, yet most properly and generally it signifies blessing; and so it may very well be understood here as a sarcastical or ironical expression, such as there are many in Scripture, as Ecclesiastes 11:9 Lamentations 4:21, and in all authors. And so the sense may be this, Bless God, and die; i.e. I see thou art set upon blessing of God; thou blessest God for giving, and thou blessest God for taking away, and thou art still blessing of God for thy loathsome and tormenting diseases, and he rewards thee accordingly, giving thee more and more of that kind of mercy for which thou blessest and praisest him. Go on therefore in this thy pious and generous course, and die as a fool dieth, and carry this reputation to thy grave, that thou hadst not common sense in thee to discern between good and evil, between thy friends and thy foes. Or rather, Awake out of this stupidity and lethargy, and give over this absurd and unreasonable practice; and as God gives thee no help nor comfort, let him lose thy praises and service. And this being her sense, it is not strange he reproveth her so sharply for it. And yet it seems hard to think that Job's wife should arrive at that height of impudence and impiety, as in plain terms to bid him curse God.
