Here are some classic protection prayers that have been used by saints through the ages. You can listen or read them.
Psalm 91 is known as the Soldiers’ Psalm. In World War I, the soldiers of the 91st Brigade recited the Psalm 91 every day. This brigade participated in three of the war’s bloodiest battles. Other units suffered up to 90% casualties, but the 91st Brigade did not suffer a single combat-related death.
Paul presented the armor of God in Ephesians 6:10-18 as one of our ways of both protecting ourselves spiritually and of also advancing God's kingdom on earth.
St. Patrick's Breastplate was used by him and his followers because they were often under attack by people involved in witchcraft. Once they had to travel by night and they recited this prayer as they walked through the dark woods. Those lying in for wait for them never saw them. They were invisible to their attackers. They are listed below, and an audio file is included for you to repeat them along with us.
1 He who dwells in the shelter of the Most High
will rest in the shadow of the Almighty.
2 I will say of the LORD, "He is my refuge and my fortress,
my God, in whom I trust."
3 Surely he will save you from the fowler's snare
and from the deadly pestilence.
4 He will cover you with his feathers,
and under his wings you will find refuge;
his faithfulness will be your shield and rampart.
5 You will not fear the terror of night,
nor the arrow that flies by day,
6 nor the pestilence that stalks in the darkness,
nor the plague that destroys at midday.
7 A thousand may fall at your side,
ten thousand at your right hand,
but it will not come near you.
8 You will only observe with your eyes
and see the punishment of the wicked.
9 If you make the Most High your dwelling—
even the LORD, who is my refuge-
10 then no harm will befall you,
no disaster will come near your tent.
11 For he will command his angels concerning you
to guard you in all your ways;
12 they will lift you up in their hands,
so that you will not strike your foot against a stone.
13 You will tread upon the lion and the cobra;
you will trample the great lion and the serpent.
14 "Because he loves me," says the LORD, "I will rescue him;
I will protect him, for he acknowledges my name.
15 He will call upon me, and I will answer him;
I will be with him in trouble,
I will deliver him and honor him.
16 With long life will I satisfy him
and show him my salvation."
Ephesians 6:10-18 The Armor of God
10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God so that you can take your stand against the devil's schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God. 18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints.
St. Patrick's Breastplate
I arise today
Through the strength of the love of Cherubim, in obedience of Angels, in the service of the Archangels, in hope of resurrection to meet with reward.
In prayers of Patriarchs, in predictions of Prophets, in preachings of Apostles, in faiths of Confessors, in innocence of Holy Virgins, in deeds of righteous men
I arise today
Through the strength of Heaven: Light of Sun, Radiance of Moon, Splendor of Fire, Speed of Lightning, Swiftness of Wind,
Depth of Sea, Stability of Earth, Firmness of Rock.
I arise today
Through God's strength to pilot me: God's might to uphold me, God's wisdom to guide me, God's eye to look before me,
God's ear to hear me, God's word to speak for me, God's hand to guard me, God's way to lie before me, God's shield to protect me,
God's host to save me
From snares of devils,
From temptation of vices,
Against inclinations of nature
From everyone who wishes me ill
Afar and anear
Alone and in a crowd.
I summon today all these powers between me(and these evils)
Against every cruel and merciless power that may oppose my body and my soul,
Against incantations of false prophetc,
Against black laws of heathenry,
Against false laws of heretics, against craft of idolotry, against spells of any witch and smiths and wizards, against every knowledge that endangers man's body and soul.
Christ to protect me today
Against poison, against burning, against drowning, against wounding,
So that there may come to me an abundance of reward.
Christ with me, Christ before me, Christ behind me, Christ in me, Christ beneath me, Christ above me,
Christ on my right, Christ on my left, Christ where I lie, Christ where I sit. Christ where I arise
Christ in the heart of every man who thinks of me, Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me, Christ in every ear that hears me.
I arise today
Through a mighty strength, the invocation of the Trinity:
Through belief in the Threeness,
Through confession of the Oneness
Towards the Creator of Creation.
Salvation is of the Lord, Salvation is of the Lord, Salvation is of Christ!
