Psalm 51:6-7 NASB Behold, You desire truth in the innermost being, And in the hidden part You will make me know wisdom. (7)Purify me with hyssop, and I shall be clean; Wash me, and I shall be whiter than snow. Psalm 51:10-12 NASB Create in me a clean heart, O God, And renew a steadfast spirit within me. [11] Do not cast me away from Your presence And do not take Your Holy Spirit from me. [12] Restore to me the joy of Your salvation And sustain me with a willing spirit.
