Passage
Giving great salvation to his king, and shewing mercy to David his anointed, and to his seed for ever.
Giving great salvation to his king, and shewing mercy to David his anointed, and to his seed for ever.
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.
2 Samuel 22:51 Giving great salvation to his king, and shewing mercy to David his anointed, and to his seed for ever.
The verse centers on "mercy", "giving", "great", "salvation", "king", "shewing", "david", and "anointed". It is saying that the verse draws attention to "mercy" and "giving", so its meaning should be read from those terms before moving to application.
The prior verse says "Therefore will I give thanks to thee...", giving immediate footing for "mercy" and "giving". In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "giving" with trust shaped by these words, not by a vague optimism outside the passage.
