Passage
And Hezekiah slept with his fathers: and Manasseh his sonne reigned in his steade.
And Hezekiah slept with his fathers: and Manasseh his sonne reigned in his steade.
2 Kings 20:19 Then Hezekiah said vnto Isaiah, The word of the Lord which thou hast spoken, is good: for saide he, Shall it not be good, if peace and trueth be in my dayes?
2 Kings 20:20 Concerning the rest of the actes of Hezekiah, and all his valiant deedes, and howe he made a poole and a cundite, and brought water into the citie, are they not written in the booke of the Chronicles of the Kings of Iudah?
2 Kings 20:21 And Hezekiah slept with his fathers: and Manasseh his sonne reigned in his steade.
The verse centers on "hezekiah", "slept", "fathers", "manasseh", "sonne", "reigned", and "steade". It is saying that the verse draws attention to "hezekiah" and "slept", so its meaning should be read from those terms before moving to application.
The prior verse says "Concerning the rest of the actes of...", giving immediate footing for "hezekiah" and "slept". In 2 Kings context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "hezekiah" and "slept" with trust shaped by these words, not by a vague optimism outside the passage.
