St. Michael, the Archangel, Jude 1:9, Prince of the Seraphim.
Jude 1:9
But when the archangel Michael, contending with the devil, was disputing about the body of Moses, he did not presume to pronounce a blasphemous judgment, but said, “The Lord rebuke you.”
St. 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, cast into Hell,
Satan and all the other evil spirits,
who prowl through the world,
seeking the ruin of souls. Amen.

Glorious St. Michael,
Prince of the heavenly hosts,
who standest always ready to give assistance
to the people of God;
who didst fight with the dragon,
the old serpent,
and didst cast him out of heaven,
and now valiantly defender of the Church of God
that the gates of hell may never prevail against her,
Please assist me also,
in the painful and dangerous conflict
which I have to sustain against the enemy.
Be with me, O mighty Prince!
that I may fight
I am so tired, please help me.
in this I pray
Amen
