Passage
Hear, O Jehovah, when I cry with my voice: Have mercy also upon me, and answer me.
Hear, O Jehovah, when I cry with my voice: Have mercy also upon me, and answer me.
Psalms 27:5 For in the day of trouble he will keep me secretly in his pavilion: In the covert of his tabernacle will he hide me; He will lift me up upon a rock.
Psalms 27:6 And now shall my head be lifted up above mine enemies round about me. And I will offer in his tabernacle sacrifices of joy; I will sing, yea, I will sing praises unto Jehovah.
Psalms 27:7 Hear, O Jehovah, when I cry with my voice: Have mercy also upon me, and answer me.
Psalms 27:8 [When thou saidst], Seek ye my face; My heart said unto thee, Thy face, Jehovah, will I seek.
Psalms 27:9 Hide not thy face from me; Put not thy servant away in anger: Thou hast been my help; Cast me not off, neither forsake me, O God of my salvation.
The verse centers on "mercy", "hear", "jehovah", "voice", "upon", and "answer". It is saying that the verse draws attention to "mercy" and "hear", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "And now shall my head be lifted..." into verse 8's "When thou saidst Seek ye my face...", so "mercy" and "hear" 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 "mercy" and "hear" with trust shaped by these words, not by a vague optimism outside the passage.
