Passage
The Lord shall thunder from heaven: and the most high shall give forth his voice.
The Lord shall thunder from heaven: and the most high shall give forth his voice.
2 Samuel 22:12 He made darkness a covering round about him: dropping waters out of the clouds of the heavens.
2 Samuel 22:13 By the brightness before him, the coals of fire were kindled.
2 Samuel 22:14 The Lord shall thunder from heaven: and the most high shall give forth his voice.
2 Samuel 22:15 He shot arrows and scattered them: lightning, and consumed them.
2 Samuel 22:16 And the overflowings of the sea appeared, and the foundations of the world were laid open at the rebuke of the Lord, at the blast of the spirit of his wrath.
The verse centers on "lord", "shall", "thunder", "heaven", "most", "high", and "give". It is saying that the verse draws attention to "lord" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "By the brightness before him the coals..." into verse 15's "He shot arrows and scattered them lightning...", so "lord" and "shall" belong inside that flow. In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "lord" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
