I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin. Selah. I acknowledged my sin - When this confession was made thoroughly and sincerely, and I ceased to cover and extenuate my offense, then thou didst forgive the iniquity of my sin. I felt the hardness of heart: I felt the deep distress of soul; I felt power to confess and abhor my sin; I felt confidence in the mercy of the Lord; and I felt the forgiveness of the iniquity of my sin.
Selah - This is all true; I know it; I felt it; I feel it.
