I remember frequently saying this prayer for priests as a seminarian

Keep them; I pray Thee, dearest Lord.
Keep them, for they are Thine
The priests whose lives burn out before
Thy consecrated shrine.

Keep them, for they are in the world,
Though from the world apart.
When earthly pleasures tempt, allure –
Shelter them in Thy heart.

Keep them and comfort them in hours
Of loneliness and pain,
When all their life of sacrifice
For souls seems but in vain.

Keep them and remember, Lord,
they have no one but Thee.
Yet, they have only human hearts,
With human frailty.

Keep them as spotless as the Host,
That daily they caress;
Their every thought and word and deed,
Deign, dearest Lord, to bless.

I grabbed that off the Spiritual Mom’s blog over in Hawaii.

As HSH readers will know, I’ve been requesting y’all to pray this prayer of Saint Michael, once for my intentions and then for all of ye who are praying this prayer. Thank you!

Sancte Michael Archangele,
defende nos in proelio;
contra nequitiam et insidias diaboli esto praesidium.
Imperet illi Deus, supplices deprecamur:
tuque, Princeps militiae Caelestis,
satanam aliosque spiritus malignos,
qui ad perditionem animarum pervagantur in mundo,
divina virtute in infernum detrude.
Amen.

Saint Michael the Archangel,
defend us in battle;
be our protection 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 into hell Satan and all the evil spirits
who prowl about the world seeking the ruin of souls.
Amen.
