What does Judges 2:19 mean?

But as soon as the judge died, they’d go right back to their old ways, acting even worse than before. They chased after other gods, served them, and worshiped them. They just wouldn’t give up their stubborn, evil habits. Judges 2:19 - Modern Text Bible

(Israel's repentance is shallow—they relapse into even deeper idolatry after each judge dies.)
