One Panel #340-341: Vade Retro Satana!

From Batman: "The Case of the Three Devils" by Bill Finger, Bob Kane, Jerry Robinson and George Roussos, Detective Comics #50 (April 1941)

Say no to evil, kids. Take it from the Batman, who defeated two devils back in 1941 using church bells.

From Cotton Carver: "Tyranny in Barlunda" by Gardner Fox and Jack Lehti, Adventure Comics #60 (April 1941)
