Job 42:1-6, 1John 1:9

1 Then Job answered the Lord, and said, 2 I know that thou canst do every thing , and that no thought can be withholden from thee. 3 Who is he that hideth counsel without knowledge? therefore have I uttered that I understood not; things too wonderful for me, which I knew not. 4 Hear, I beseech thee, and I will speak: I will demand of thee, and declare thou unto me. 5 I have heard of thee by the hearing of the ear: but now mine eye seeth thee. 6 Wherefore I abhor myself , and repent in dust and ashes.
1 John 1:9
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
