Prayer to St. Michael:

​Holy Michael the Archangel, defend us in the day of battle. Be our safeguard against the wickedness and snares of the devil. May God rebuke him, we humbly pray. And do thou, O Prince of the heavenly host, by the power of God, thrust down into hell Satan and all the wicked spirits who wander through the world, for the ruin of souls.  Amen.
