Judges 6:31-32

31Joash said to the angry men who were against him, ‘Are you trying to save Baal because he is in trouble? Why should you do that? Anyone who tries to help Baal will die before tomorrow arrives. If Baal really is a god, he should fight for himself. It is his altar that someone has pulled down!’

32So after that, people called Gideon ‘Jerub-Baal’. That was because Joash had said, ‘Baal should fight for himself. He himself should punish the person who pulled down his altar.’
