Job 13:15 - Ellicott's Commentary On The Whole Bible

Though he slay me, yet will I trust in him. — This rendering is almost proverbial; but, to say the least, its accuracy is very doubtful, for the better reading does not warrant it, but runs thus: Behold He will slay me. I have no hope; yet will I maintain my ways before Him. It is true we thus lose a very beautiful and familiar resolve; but the expression of living trust is not less vivid. For though there is, as there can be, no gleam of hope for victory in this conflict, yet, notwithstanding, Job will not forego his conviction of integrity; for the voice of conscience is the voice of God, and if he knows himself to be innocent, he would belie and dishonour God as well as himself in renouncing his innocence.
