Passage
God who giveth me revenge, and bringest down people under me,
God who giveth me revenge, and bringest down people under me,
2 Samuel 22:46 The strangers are melted away, and shall be straitened in their distresses.
2 Samuel 22:47 The Lord liveth, and my God is blessed: and the strong God of my salvation shall be exalted:
2 Samuel 22:48 God who giveth me revenge, and bringest down people under me,
2 Samuel 22:49 Who bringest me forth from my enemies, and liftest me up from them that resist me: from the wicked man thou shalt deliver me.
2 Samuel 22:50 Therefore will I give thanks to thee, O Lord, among the Gentiles, and will sing to thy name.
The verse centers on "giveth", "revenge", "bringest", "down", "people", and "under". It is saying that the verse draws attention to "giveth" and "revenge", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 47's "The Lord liveth and my God is..." into verse 49's "Who bringest me forth from my enemies...", so "giveth" and "revenge" 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 "giveth" and "revenge" with trust shaped by these words, not by a vague optimism outside the passage.
