Psalm 51: 1 Have mercy on me, O God,
according to your unfailing love;
according to your great compassion
blot out my transgressions.
2 Wash away all my iniquity
and cleanse me from my sin.
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.

Psalm 139: 23 Search me, God, and know my heart;
test me and know my anxious thoughts.
24 See if there is any offensive way in me,
and lead me in the way everlasting.

Psalm 103: 10 He does not treat us as our sins deserve
or repay us according to our iniquities.
11 For as high as the heavens are above the earth,
so great is His love for those who fear Him;
12 as far as the east is from the west,
so far has He removed our transgressions from us.
13 As a father has compassion on his children,
so the Lord has compassion on those who fear Him;
