Psalm 51:1-2, 7, 9
1 To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba. Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
2 Wash me thoroughly from mine iniquity, and cleanse me from my sin.
7 Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
9 Hide thy face from my sins, and blot out all mine iniquities.
Daniel 9:17-19
17 Now therefore, O our God, hear the prayer of thy servant, and his supplications, and cause thy face to shine upon thy sanctuary that is desolate, for the Lord's sake.
18 O my God, incline thine ear, and hear; open thine eyes, and behold our desolations, and the city which is called by thy name: for we do not present our supplications before thee for our righteousnesses, but for thy great mercies.
19 O Lord, hear; O Lord, forgive; O Lord, hearken and do; defer not, for thine own sake, O my God: for thy city and thy people are called by thy name.
