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.
My sin - (2 Samuel 12:13.)
Not hid - or "covered;" the same Hebrew as in Psalms 32:1. He only has his sins covered who does not himself cover them (Hengstenberg).
I will confess my transgressions - in contrast to his former "guile" (Psalms 32:2) and "keeping silence" (Psalms 32:3) I will confess my transgressions - in contrast to his former "guile" (Psalms 32:2) and "keeping silence" (Psalms 32:3).
Iniquity of my sin - (Proverbs 28:13.) He designedly repeats the same three terms, 'transgressions, iniquity, sin,' as in Psalms 32:1-2, to imply that his experience confirms the general truth stated at the outset-namely, the blessedness of guileless confession of all sin, and of its consequent forgiveness.
