Passage
And he sent his arrows, and scattered [mine enemies]; and he shot forth lightnings, and discomfited them.
And he sent his arrows, and scattered [mine enemies]; and he shot forth lightnings, and discomfited them.
Psalms 18:12 From the brightness before him his thick clouds passed forth: hail and coals of fire.
Psalms 18:13 And Jehovah thundered in the heavens, and the Most High uttered his voice: hail and coals of fire.
Psalms 18:14 And he sent his arrows, and scattered [mine enemies]; and he shot forth lightnings, and discomfited them.
Psalms 18:15 And the beds of the waters were seen, and the foundations of the world were uncovered at thy rebuke, Jehovah, at the blast of the breath of thy nostrils.
Psalms 18:16 He reached forth from above, he took me, he drew me out of great waters:
The verse centers on "light", "sent", "arrows", "scattered", "mine", "enemies", "shot", and "forth". It is saying that the verse draws attention to "light" and "sent", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "And Jehovah thundered in the heavens and..." into verse 15's "And the beds of the waters were...", so "light" and "sent" 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 "light" and "sent" with trust shaped by these words, not by a vague optimism outside the passage.
