Passage
Jehovah liveth; and blessed be my rock; and exalted be the God of my salvation,
Jehovah liveth; and blessed be my rock; and exalted be the God of my salvation,
Psalms 18:44 At the hearing of the ear, they obey me: strangers come cringing unto me.
Psalms 18:45 Strangers have faded away, and they come trembling forth from their close places.
Psalms 18:46 Jehovah liveth; and blessed be my rock; and exalted be the God of my salvation,
Psalms 18:47 The God who hath avenged me, and hath subjected the peoples to me;
Psalms 18:48 Who hath delivered me from mine enemies: yea, thou hast lifted me up above them that rose up against me; from the man of violence hast thou delivered me.
The verse centers on "jehovah", "liveth", "blessed", "rock", "exalted", and "salvation". It is saying that the verse draws attention to "jehovah" and "liveth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 45's "Strangers have faded away and they come..." into verse 47's "The God who hath avenged me and...", so "jehovah" and "liveth" 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 "jehovah" and "liveth" with trust shaped by these words, not by a vague optimism outside the passage.
