John Gill Commentary 2 Chronicles 15:19

"And there was no more war unto the five and thirtieth year of the reign of Asa." — 2 Chronicles 15:19 (ASV)

And there was no more war until the thirty fifth year of the
reign of Asa .
] That is, from the Ethiopian war to that time; after that there was no war with any foreign enemy; there were animosities and discords, bickerings and hostilities of some sort continually between Asa and Baasha king of Israel, as long as he lived, see (1 Kings 15:16 1 Kings 15:32) .
