Then Nathan sayde vnto the King, Go, and doe all that is in thine heart: for the Lord is with thee.
Then Nathan sayde vnto the King, Go, and doe all that is in thine heart: for the Lord is with thee.
2 Samuel 7:1 Afterwarde when the King sate in his house and the Lord had giuen him rest rounde about from all his enemies,
2 Samuel 7:2 The King saide vnto Nathan the Prophet, Beholde, nowe I dwel in an house of cedar trees, and the Arke of God remayneth within the curtaines.
2 Samuel 7:3 Then Nathan sayde vnto the King, Go, and doe all that is in thine heart: for the Lord is with thee.
2 Samuel 7:4 And the same night the worde of the Lord came vnto Nathan, saying,
2 Samuel 7:5 Goe and tell my seruant Dauid, Thus saieth the Lord, Shalt thou buylde me an house for my dwelling?
The verse centers on "nathan", "sayde", "vnto", "king", "thine", "heart", "lord", and "thee". It is saying that the verse draws attention to "nathan" and "sayde", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "The King saide vnto Nathan the Prophet..." into verse 4's "And the same night the worde of...", so "nathan" and "sayde" 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 "nathan" and "sayde" with trust shaped by these words, not by a vague optimism outside the passage.
