When he shall be judged; when he shall be called to an account, and his cause examined before thy tribunal. Let his prayer become sin, i.e. be turned into sin, or be imputed to him as his sin, or be as unavailable with God for his relief as his sins. When he makes supplication to his Judge, as Job speaks, Job 9:15, for pity and pardon, let him be the more provoked and enraged by it.
