Armour of God (Ephesians 6:10–20)
Lord God, I pray for your strength and mighty power, to be clothed with the armour of God so that I may be able to stand against the deceits of the devil – for our wrestling is not against flesh and blood, but against principalities and powers; against the rulers of the world of this darkness; against the spirits of wickedness in high places. I take unto myself the armour of God so that I may be able to resist evil today and stand in all things perfect. Gird my loins with the truth and arm me with the breastplate of justice. Shod my feet with the preparation of the Gospel of peace. In all things, give me the shield of faith to extinguish the fiery darts of the evil one. I take unto myself the helmet of salvation and the sword of the Spirit, which is the Word of God; at all times praying and supplicating in the Spirit, watching and offering petitions for all the saints. Give me speech so that I may open my mouth with confidence to make known the mystery of the Gospel, for which I am an ambassador in a chain, so that I may boldly speak as I ought to. Amen.
Psalm 91 (Douay-Rheims Psalm 90)
I dwell with the help of the Most High. I abide under the protection of the God of heaven. You are my protector and my refuge. My Lord, my God, I trust in you, for you have delivered me from the snare of the hunters and from piercing words. Overshadow me with your shoulders, and under your wings I place my trust. Let your truth compass me with a shield. I am not afraid of the terror of the night, of the arrow that flies in the day, of the business that haunts in the dark, of invasion or of the noonday devil – even if a thousand shall fall at my side and ten thousand at my right hand – it will not come near me. But even so, you will consider with your eyes and see the retribution of the wicked, because you, O Lord, are my hope. I have made the Most High my refuge. No evil will come to me, nor will the scourge come near my dwelling, for you have given your angels charge over me to keep me in all your ways. In their hands they will bear me up, lest I dash my foot against a stone. I will walk upon the viper and the basilisk , and will trample underfoot the lion and the dragon. Because I hoped in you, you will deliver me. You will protect me because I have known your name. I will cry to you and you will hear me. You are with me in tribulation. You will deliver me and you will exalt me. You will fill me with length of days and you will show me your salvation. Amen.
Psalm 23 (Douay-Rheims Psalm 22)
The Lord rules over me and there is nothing I shall want. He has set me in a place of pasture. He has brought me up on the water of refreshment. He has converted my soul. He has led me on the paths of justice for his own name’s sake. Even though I should walk in the midst of the shadow of death, I will fear no evil, for you are with me. Your rod and your staff have comforted me. You have prepared a table before me in the face of those who afflict me. You have anointed my head with oil, and my chalice, which inebriates me with your splendour. And your mercy will follow me all the days of my life so that I may dwell in the house of the Lord for the length of days. Amen.
 A basilisk is a legendary, extremely venomous snakelike dragon or reptile, with a lethal stare or breath. In this context, it refers to an evil spirit in the same way that the dragon refers to Satan.
