Passage
Jehovah liveth--and blessed <FI>is<Fi> my rock, And exalted is the God of my salvation.
Jehovah liveth--and blessed <FI>is<Fi> my rock, And exalted is the God of my salvation.
Psalms 18:44 At the hearing of the ear they hearken to me, Sons of a stranger feign obedience to me,
Psalms 18:45 Sons of a stranger fade away, And are slain out of their close places.
Psalms 18:46 Jehovah liveth--and blessed <FI>is<Fi> my rock, And exalted is the God of my salvation.
Psalms 18:47 God--who is giving vengeance to me, And He subdueth peoples under me,
Psalms 18:48 My deliverer from mine enemies, Above my withstanders Thou raisest me, From a man of violence dost deliver me.
The verse centers on "jehovah", "liveth--and", "blessed", "rock", "exalted", and "salvation". It is saying that the verse draws attention to "jehovah" and "liveth--and", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 45's "Sons of a stranger fade away And..." into verse 47's "God--who is giving vengeance to me And...", so "jehovah" and "liveth--and" 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--and" with trust shaped by these words, not by a vague optimism outside the passage.
