Contradiction with Proverbs 19:23
Proverbs 19:23 says, "The fear of the LORD tendeth to life: and he that hath it shall abide satisfied; he shall not be visited with evil." This contrasts with Job 31:23, where Job is expressing a fear of destruction from God, suggesting that despite fearing God, he could still face calamity.
Proverbs 19:23: The fear of the LORD [tendeth] to life: and [he that hath it] shall abide satisfied; he shall not be visited with evil.
