Passage
And there was no warre vnto the fiue and thirtieth yeere of the reigne of Asa.
And there was no warre vnto the fiue and thirtieth yeere of the reigne of Asa.
2 Chronicles 15:17 But the hie places were not taken away out of Israel: yet the heart of Asa was perfit all his dayes.
2 Chronicles 15:18 Also he brought into the house of God the things that his father had dedicate, and that he had dedicate, siluer, and golde, and vessels.
2 Chronicles 15:19 And there was no warre vnto the fiue and thirtieth yeere of the reigne of Asa.
The verse centers on "warre", "vnto", "fiue", "thirtieth", "yeere", and "reigne". It is saying that the verse draws attention to "warre" and "vnto", so its meaning should be read from those terms before moving to application.
The prior verse says "Also he brought into the house of...", giving immediate footing for "warre" and "vnto". In 2 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "warre" and "vnto" with trust shaped by these words, not by a vague optimism outside the passage.
