(Before It's News)
1 Blessed is he whose transgression is forgiven, whose sin is covered.
2 Blessed is the man to whom the LORD imputes no iniquity, and in whose spirit there is no deceit.
5 I acknowledged my sin to thee, and I did not hide my iniquity; I said, “I will confess my transgressions to the LORD”; then thou didst forgive the guilt of my sin. [Selah]
6 Therefore let every one who is godly offer prayer to thee; at a time of distress, in the rush of great waters, they shall not reach him.
7 Thou art a hiding place for me, thou preservest me from trouble; thou dost encompass me with deliverance. [Selah]
