LXX2012(i)
1 (51) For the end, a Psalm of David, when Nathan the prophet came to him, when he had gone to Bersabee. Have mercy upon me, O God, according to your great mercy; and according to the multitude of your compassions blot out my transgression.
2 Wash me thoroughly from mine iniquity, and cleanse me from my sin.
3 For I am conscious of mine iniquity; and my sin is continually before me.
