Psalm 32:4-5

4For day and night your hand was heavy on me; my strength was sapped as in the heat of summer. The Hebrew has Selah (a word of uncertain meaning) here and at the end of verses 5 and 7.

5Then I acknowledged my sin to you and did not cover up my iniquity. I said, “I will confess my transgressions to the LORD .” And you forgave the guilt of my sin.
