From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
To Stay a Shot.
Three drops of blood flowed over the holy face of our Lord. These three holy blood drops are moved before the touch-hole of the weapon, and remain as pure as the mother of God. No more shall fire and smoke from thy barrel and touch-hole go. Gun, let neither fire nor smoke from thy barrel move, nor heat. Now, I go thither, because God the Lord moves with me; God the Son accompanies me; God the Holy Ghost, he soars o'er me forever and ever, that bullet and sword will hurt me never. + + + Three times.
