The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 49
Of Many who were Swallowed up by the Earth, and how the rest were Converted unto God.
But the heart of Leogaire was hardened, as was formerly the heart of Pharao before Moses against the commands of the Lord. For though so many miracles had been wrought, he feared not to provoke the high God, and to offend his servant Patrick. Therefore, showing himself to be a second Nero, in revenge for the death of the evil-doer, he appointed several of his people to destroy the saint. And, as is testified by the Holy Writ, a wicked prince always hath wicked ministers, many of his servants put themselves forward, voluntary, prompt, and earnest to so great a sacrilege. But God, the all-powerful protector of His beloved, armed the zeal of the creature against these senseless idolaters, and ere they could effect their wickedness he swept them from the earth and destroyed them. For the earth opened and swallowed them up, and so many of the people of Teamhrach as were consenting thereto; and the abyss opened its mouth and devoured them, even alive. And they who remained, and all the dwellers of that land seeing or hearing of these things, feared with mighty fear; and, lest they should be punished with the like punishment, they believed in Christ, and crowded together unto the font. And the king trembled, and threw himself at the feet of Patrick, and besought pardon, and promised that he would thenceforth obey him. And the saint forgave him; yet, though he a long time instructed him in the faith of the Lord Jesus, in no wise could he persuade him unto baptism. Therefore he dismissed him, that, following his free will, he might go on in the inventions of his own heart, nor seem to be compelled unto the faith; yet, at the revelation of the Spirit, what he foreknew of the king and his posterity thus was prophesied by the saint: "Since thou hast always resisted my doctrine, nor ceased to afflict me beyond measure; moreover, since thou thoughtest scorn to believe in the Creator of all things, therefore art thou the child of perdition, and thou, with all that were partners in thine offence, shouldst justly, even at this instant, go into eternal punishment; but since thou humbly besought of me forgiveness, and, like the King Achab, hast humbled thyself before my God, the Lord will not at this time bring on thee the evil which thou hast deserved; yet shall none of thy seed sit on thy throne after thee, but they shall become servants unto thy brother, who will believe in Christ, and to his posterity for ever and ever." But the queen believed in Christ, and was baptized and blessed of Patrick, and at length, with a pious end, rested in the Lord. And he went forward with his people, baptizing in the name of the Holy Trinity all those who believed, while the Lord assisted and confirmed his labors with manifold miracles.
