Psalms 51:14-15

Deliver me from blood-guiltiness Hebrew, מדמים, middamim, from bloods, because he had been the cause of the death, not only of Uriah, but of others of the Lord's people with him, 2 Samuel 11:17. My tongue shall sing of thy righteousness, of thy faithfulness in making good thy promises; or, rather, of thy clemency and goodness, as the word righteousness often signifies. Open thou my lips Which are shut with shame, and grief, and horror. Restore unto me the opportunity, ability, and liberty which I formerly had of speaking to thee in prayer and praise, and to my fellow-creatures, by way of instruction, reproof, or exhortation, with freedom and boldness. And my mouth shall show forth thy praise In thy mercy and thy faithfulness remember thy gracious promises, and accomplish them, notwithstanding my unworthiness, and, as I shall be furnished with new motives and occasions for gratitude and thankfulness, my mouth shall everywhere declare thy goodness, to thy perpetual praise and glory.
