Passage
Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
Psalms 51:12 Restore unto me the joy of thy salvation; and uphold me with thy free spirit.
Psalms 51:13 Then will I teach transgressors thy ways; and sinners shall be converted unto thee.
Psalms 51:14 Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
Psalms 51:15 O Lord, open thou my lips; and my mouth shall shew forth thy praise.
Psalms 51:16 For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering.
The verse centers on "deliver", "bloodguiltiness", "thou", "salvation", "tongue", "shall", "sing", and "aloud". It is saying that the verse draws attention to "deliver" and "bloodguiltiness", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Then will I teach transgressors thy ways..." into verse 15's "O Lord open thou my lips and...", so "deliver" and "bloodguiltiness" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "deliver" and "bloodguiltiness" with trust shaped by these words, not by a vague optimism outside the passage.
