Psalm 32 is one of the seven penitential psalm. This designation was given to it by the Church. The designations in the biblical text say, “Of David” and “Maskil.” A Maskil seems to be a literary or musical term. I’m guessing it means that the song was written in the key of G (:
The psalm begins with a couple of beatitudes. beatitude states a blessing or a condition of happiness. “Blessed are. . . ” or “Happy are . . . ” is the normal translation/formula. These beatitudes emphasize the blessing of forgiveness and restored innocence (Psalm 32:1-2).
The second part of the Psalm–Psalm 32:3-5–emphasizes the damaging effect of withholding the Psalmist’s sin from the Lord. It had both psychological and physiological effects. The ancients understood intuitively what we are only recently rediscovering–that the Spirit, Mind and Body interact in dynamic and integrated ways. Psalm 32:5 is the turning point in the Psalmist’s difficulties, “I acknowledged my sin to you, and I did not hide my iniquity; I said, ‘I will confess my transgressions to the Lord,’ and you forgave the guilt of my sin.” It prefaces the promise in 1 John 1:9, “If we confess our sins, God is faithful and just to forgive us our sins and cleanse us of all unrighteousness.”
The Psalm then moves toward an instructive place. The Psalmist instructs those who would listen about the necessity of listening.
