Albert Barnes Commentary Job 13:17

"Hear diligently my speech, And let my declaration be in your ears." — Job 13:17 (ASV)

Hear diligently my speech - The speech which I have made; that is, the declaration which I have made of my innocence. He refers to his solemn declaration (Job 13:15–16) that he had unwavering confidence in God, and that even if God should slay him, he would put his confidence in him. This solemn appeal he wished them to attend to as one of the utmost importance.
