2 Kings 14:10

Thou hast indeed smitten Edom, and thine heart hath lifted
thee up
Swelled him with pride and vanity on account of the victory he had obtained over the Edomites; which pride was at the bottom of his message to him, and that goes before a fall: ( Proverbs 16:18 )

glory of this, and tarry at home;
be content with the glory of it, and boast of it at home, but do not swagger abroad, and insult thy neighbours:

for why shouldest thou meddle to thy hurt, that thou shouldest fall,
even thou, and Judah with thee?
suggesting to him, that he had better be quiet, since it would be to the harm, if not the ruin, of him and his kingdom.
