NET

19 You defeated Edom and it has gone to your head. Gloat over your success, but stay in your palace. Why bring calamity on yourself? Why bring down yourself and Judah along with you?”

Darby

19 Thou thinkest, Lo, thou hast smitten Edom; and thy heart has lifted thee up to boast: abide now at home; why shouldest thou contend with misfortune, that thou shouldest fall, thou and Judah with thee?

KJV

19 Thou sayest, Lo, thou hast smitten the Edomites; and thine heart lifteth thee up to boast: abide now at home; why shouldest thou meddle to [thine] hurt, that thou shouldest fall, [even] thou, and Judah with thee?
