Job 13:15-18 (KJV)
15 Though he slay me, yet will I trust in him: but I will maintain mine own ways before him.
16 He also shall be my salvation: for an hypocrite shall not come before him.
17 Hear diligently my speech, and my declaration with your ears.
18 Behold now, I have ordered my cause; I know that I shall be justified.
Job 13
