Passage
The LORD also thundered in the heavens, and the Highest gave his voice; hail stones and coals of fire.
The LORD also thundered in the heavens, and the Highest gave his voice; hail stones and coals of fire.
Psalms 18:11 He made darkness his secret place; his pavilion round about him were dark waters and thick clouds of the skies.
Psalms 18:12 At the brightness that was before him his thick clouds passed, hail stones and coals of fire.
Psalms 18:13 The LORD also thundered in the heavens, and the Highest gave his voice; hail stones and coals of fire.
Psalms 18:14 Yea, he sent out his arrows, and scattered them; and he shot out lightnings, and discomfited them.
Psalms 18:15 Then the channels of waters were seen, and the foundations of the world were discovered at thy rebuke, O LORD, at the blast of the breath of thy nostrils.
The verse centers on "lord", "thundered", "heavens", "highest", "gave", "voice", "hail", and "stones". It is saying that the verse draws attention to "lord" and "thundered", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "At the brightness that was before him..." into verse 14's "Yea he sent out his arrows and...", so "lord" and "thundered" 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 "lord" and "thundered" with trust shaped by these words, not by a vague optimism outside the passage.
