25 What folly it was to include Elijah and Elisha in a list of married men, is plain without a word from me. For, since John Baptist came in the spirit and power of Elijah, and John was a virgin, it is clear that he came not only in Elijah's spirit, but also in his bodily chastity. Then the passage relating to Hezekiah might be adduced (though Jovinianus with his wonted stupidity did not notice it), in which after his recovery and the addition of fifteen years to his life he said, “Now will I beget children.”
It must be remembered, however, that in the Hebrew texts the passage is not so, but runs thus: “The father to the children shall make known your faithfulness.” Nor need we wonder that Huldah, the prophetess, and wife of Shallum, was consulted by Josiah, King of Judah, when the captivity was approaching and the wrath of the Lord was falling upon Jerusalem: since it is the rule of Scripture when holy men fail, to praise women to the reproach of men. And it is superfluous to speak of Daniel, for the Hebrews to the present day affirm that the three youths were eunuchs, in accordance with the declaration of God which Isaiah utters to Hezekiah: “And of your sons that shall issue from you, which you shall beget, shall they take away: and they shall be eunuchs in the palace of the King of Babylon.”
And again in Daniel we read: “And the king spoke unto Ashpenaz the master of his eunuchs, that he should bring in certain of the children of Israel, even of the seed royal and of the nobles: youth in whom was no blemish, but well favoured, and skilful in all wisdom, and cunning in knowledge, and understanding science.” The conclusion is that if Daniel and the three youths were chosen from the seed royal, and if Scripture foretold that that there should be eunuchs of the seed royal, these men were those who were made eunuchs.
If he meets us with the argument that in Ezekiel it is said that Noah, Daniel and Job in a sinful land could not free their sons and daughters, we reply that the words are used hypothetically. Noah and Job were not in existence at that time: we know that they lived many ages before. And the meaning is this: if there were such and such men in a sinful land, they shall not be able to save their own sons and daughters: because the righteousness of the father shall not save the son, nor shall the sin of one be imputed to another. “For the soul that sins, it shall die.”
This, too, must be said, that Daniel, as the history of his book shows, was taken captive with King Jehoiakim at the same time that Ezekiel was also led into captivity. How then could he have sons who was still a youth? And only three years had elapsed when he was brought in to wait upon the king. Let no one suppose that Ezekiel at this time remembers Daniel as a man, not as a youth; for “It came to pass,” he says, “in the sixth year,” that is of King Jehoiakim, “in the sixth month, in the fifth day of the month:” and, “as I sat in my house, and the elders of Judah sat before me.”
Yet on that same day it was said to him, “Though these three men, Noah, Daniel, and Job were in it.” Daniel was therefore a youth, and known to the people, either on account of his interpretation of the king's dreams, or on account of the release of Susannah, and the slaying of the elders. And it is clearly proved that at the time these things were spoken of Noah, Daniel, and Job, Daniel was still a youth and could not have had sons and daughters, whom he might save by his righteousness. So far concerning the Law.
