Psalm 51:10-13

10 Create in me a pure heart, O God,
and renew a steadfast spirit within me.
11 Do not cast me from your presence
or take your Holy Spirit from me.
12 Restore to me the joy of your salvation
and grant me a willing spirit, to sustain me.
13 Then I will teach transgressors your ways,
and sinners will turn back to you.
