The sons of Levi...shall storm against the world, they shall strike the devil and his crew, and they shall pierce through and through, for life or for death, with their two-edged sword of the Word of God, all those to whom they shall be sent on the part of the Most High. par. 56-57
Below is the full quote regarding The Most Blessed Virgin Mary's purifying work in the world through her holy priests. I copy it from The Rosary Trail.

55. In a word, God wishes that His holy Mother should be at present more known, more loved, more honored than she has ever been. This, no doubt, will take place if the predestinate enter, with the grace and light of the Holy Ghost, into the interior and perfect practice which I will disclose to them shortly. Then they will see clearly, as far as faith allows, that beautiful Star of the Sea. They will arrive happily in harbor, following its guidance, in spite of the tempests and the pirates. They will know the grandeurs of that Queen, and will consecrate themselves entirely to her service as subjects and slaves of love. They will experience her sweetness and her maternal goodness, and they will love her tenderly like well-beloved children. They will know the mercies of which she is full, and the need they have of her help; and they will have recourse to her in all things, as to their dear advocate and Mediatrix with Jesus Christ. They will know what is the surest, the easiest, the shortest and the most perfect means of going to Jesus Christ; and they will give themselves to Mary, body and soul, without reserve, that they may thus belong entirely to Jesus Christ.
56. But who shall those servants, slaves and children of Mary be? They shall be the ministers of the Lord who, like a burning fire, shall kindle the fire of divine love everywhere. They shall be “like sharp arrows in the hand of the powerful” Mary to pierce her enemies. (Ps. 126:4). They shall be the sons of Levi, well purified by the fire of great tribulation, and closely adhering to God (1 Cor. 6:17), who shall carry the gold of love in their heart, the incense of prayer in their spirit, and the myrrh of mortification in their body. They shall be everywhere the good odor of Jesus Christ to the poor and to the little, while at the same time, they shall be an odor of death to the great, to the rich and to the proud worldlings.
57. They shall be clouds thundering and flying through the air at the least breath of the Holy Ghost; who, detaching themselves from everything and troubling themselves about nothing, shall shower forth the rain of the Word of God and of life eternal. They shall thunder against sin; they shall storm against the world; they shall strike the devil and his crew; and they shall pierce through and through, for life or for death, with their two-edged sword of the Word of God (Eph. 6:17), all those to whom they shall be sent on the part of the Most High.
58. They shall be the true apostles of the latter times, to whom the Lord of Hosts shall give the word and the might to work marvels and to carry off with glory the spoils of His enemies. They shall sleep without gold or silver, and, what is more, without care, in the midst of the other priests, ecclesiastics, and clerics (Ps. 67:14); and yet they shall have the God and the salvation of souls, wheresoever the Holy Ghost shall call them. Nor shall they leave behind them, in the places where they have preached, anything but the gold of charity, which is the fulfillment of the whole law. (Rom. 13:10)
59. In a word, we know that they shall be true disciples of Jesus Christ, walking in the footsteps of His poverty, humility, contempt of the world, charity; teaching the narrow way of God in pure truth, according to the holy Gospel, and not according to the maxims of the world; troubling themselves about nothing; not accepting persons; sparing, fearing and listening to no mortal, however influential he may be. They shall carry on their shoulders the bloody standard of the Cross, the Crucifix in their right hand and the Rosary in their left, the sacred Names of Jesus and Mary in their hearts, and the modesty and mortification of Jesus Christ in their own behaviour.
These are the great men who are to come; but Mary is the one who, by order of the Most High, shall fashion them for the purpose of extending His empire over that if the impious, the idolaters and the Mahometans. But when and how shall this be? God alone knows.
As for us, we have to hold our tongues, to pray, to sigh and to wait: “With expectation I have waited.” (Ps. 39:2)
