Passage
Lord, open my lips. My mouth shall declare your praise.
Lord, open my lips. My mouth shall declare your praise.
Psalms 51:13 Then I will teach transgressors your ways. Sinners shall be converted to you.
Psalms 51:14 Deliver me from the guilt of bloodshed, O God, the God of my salvation. My tongue shall sing aloud of your righteousness.
Psalms 51:15 Lord, open my lips. My mouth shall declare your praise.
Psalms 51:16 For you don’t delight in sacrifice, or else I would give it. You have no pleasure in burnt offering.
Psalms 51:17 The sacrifices of God are a broken spirit. A broken and contrite heart, O God, you will not despise.
The verse centers on "lord", "open", "lips", "mouth", "shall", "declare", and "praise". It is saying that the verse draws attention to "lord" and "open", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "Deliver me from the guilt of bloodshed..." into verse 16's "For you don t delight in sacrifice...", so "lord" and "open" 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 "lord" and "open" with trust shaped by these words, not by a vague optimism outside the passage.
