Book One (Psalms 1-41) "Concerning Man"
A Psalm of David, Maschil.
1: 
Blessed is he whose transgression is forgiven, whose sin is covered.
2: Blessed is the man unto whom the LORD imputeth not iniquity,
and in whose spirit there is no guile.
3: When I kept silence, my bones waxed old through my roaring all the day long.
4: For day and night thy hand was heavy upon me: my moisture is turned into the drought of summer. Selah.
5: 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.
6: For this shall every one that is godly pray unto thee in a time when thou mayest be found: surely in the floods of great waters they shall not come nigh unto him.
7: Thou art my hiding place; thou shalt preserve me from trouble; thou shalt compass me about with songs of deliverance. Selah.
8: I will instruct thee and teach thee in the way which thou shalt go: I will guide thee with mine eye.
9: Be ye not as the horse, or as the mule, which have no understanding: whose mouth must be held in with bit and bridle, lest they come near unto thee.
10: Many sorrows shall be to the wicked:
but he that trusteth in the LORD, mercy shall compass him about.
11: Be glad in the LORD, and rejoice, ye righteous:
and shout for joy, all ye that are upright in heart.
