Passage
Then the channels of waters appeared, And the foundations of the world were laid bare, At thy rebuke, O Jehovah, At the blast of the breath of thy nostrils.
Then the channels of waters appeared, And the foundations of the world were laid bare, At thy rebuke, O Jehovah, At the blast of the breath of thy nostrils.
Psalms 18:13 Jehovah also thundered in the heavens, And the Most High uttered his voice, Hailstones and coals of fire.
Psalms 18:14 And he sent out his arrows, and scattered them; Yea, lightnings manifold, and discomfited them.
Psalms 18:15 Then the channels of waters appeared, And the foundations of the world were laid bare, At thy rebuke, O Jehovah, At the blast of the breath of thy nostrils.
Psalms 18:16 He sent from on high, he took me; He drew me out of many waters.
Psalms 18:17 He delivered me from my strong enemy, And from them that hated me; for they were too mighty for me.
The verse centers on "world", "channels", "waters", "appeared", "foundations", "laid", "bare", and "rebuke". It is saying that the verse draws attention to "world" and "channels", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "And he sent out his arrows and..." into verse 16's "He sent from on high he took...", so "world" and "channels" 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 "world" and "channels" with trust shaped by these words, not by a vague optimism outside the passage.
