Job was really looking for answers, and he was not hiding from any sin he may have committed. He opened himself up to God’s examination in order to confess and repent. It is so easy to try to hide our sin. How much better to confess and receive the forgiveness of our willing God.
Job 13:20-23 ESV
[20] Only grant me two things, then I will not hide myself from your face: [21] withdraw your hand far from me, and let not dread of you terrify me. [22] Then call, and I will answer; or let me speak, and you reply to me. [23] How many are my iniquities and my sins? Make me know my transgression and my sin.
