John Gill Commentary 1 Kings 12:13

"And the king answered the people roughly, and forsook the counsel of the old men which they had given him," — 1 Kings 12:13 (ASV)

And the king answered the people roughly
In a blustering manner, gave them hard words and severe menaces, being worked up to such a spirit by his young counsellors:

and forsook the old men's counsel that they gave him :
to give them good words and kind promises.
