Passage
For it is thou that savest the afflicted people; but the haughty eyes wilt thou bring down.
For it is thou that savest the afflicted people; but the haughty eyes wilt thou bring down.
Psalms 18:25 With the gracious thou dost shew thyself gracious; with the upright man thou dost shew thyself upright;
Psalms 18:26 With the pure thou dost shew thyself pure; and with the perverse thou dost shew thyself contrary.
Psalms 18:27 For it is thou that savest the afflicted people; but the haughty eyes wilt thou bring down.
Psalms 18:28 For it is thou that makest my lamp to shine: Jehovah my God enlighteneth my darkness.
Psalms 18:29 For by thee I have run through a troop; and by my God have I leaped over a wall.
The verse centers on "thou", "savest", "afflicted", "people", "haughty", "eyes", and "wilt". It is saying that the verse draws attention to "thou" and "savest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "With the pure thou dost shew thyself..." into verse 28's "For it is thou that makest my...", so "thou" and "savest" 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 "thou" and "savest" with trust shaped by these words, not by a vague optimism outside the passage.
