What does 2 Kings 10:25 mean?

As soon as Jehu finished offering the burnt offering, he ordered the guards and officers, 'Go in and kill them all. Don’t let anyone get away.' So they killed everyone with swords and dragged the bodies out. Then they went into the inner room of Baal’s temple, 2 Kings 10:25 - Modern Text Bible

(Jehu’s men carry out a total massacre, killing every Baal worshiper present.)
