And He sendeth His arrows and scattereth them, And much lightning, and crusheth them.
And He sendeth His arrows and scattereth them, And much lightning, and crusheth them.
Psalms 18:12 From the brightness over-against Him His thick clouds have passed on, Hail and coals of fire.
Psalms 18:13 And thunder in the heavens doth Jehovah, And the Most High giveth forth His voice, Hail and coals of fire.
Psalms 18:14 And He sendeth His arrows and scattereth them, And much lightning, and crusheth them.
Psalms 18:15 And seen are the streams of waters, And revealed are foundations of the earth. From Thy rebuke, O Jehovah, From the breath of the spirit of Thine anger.
Psalms 18:16 He sendeth from above--He taketh me, He draweth me out of many waters.
The verse centers on "light", "sendeth", "arrows", "scattereth", "much", "lightning", and "crusheth". It is saying that the verse draws attention to "light" and "sendeth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "And thunder in the heavens doth Jehovah..." into verse 15's "And seen are the streams of waters...", so "light" and "sendeth" 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 "sendeth" with trust shaped by these words, not by a vague optimism outside the passage.
