provide evidence that William and other reformers where futurists that claim there is a gap between Daniel's 69th and 70th week?
I do not have William Lowth's commentary on Daniel. But I have already posted MANY plainly futuristic comments from his other work in the (Dispensationalists only) thread "The Futurism of William Lowth."
But A future fulfillment was very clearly taught in ancient times by Hippolytus in his Commentary on Daniel." This is the very oldest surviving Christian commentary on scripture. Hippolytus said:
“For after sixty-two weeks was fulfilled and after Christ has come and the Gospel has been preached in every place, times having been spun out, the end remains one week away, in which Elijah and Enoch shall be present and in its half the abomination of desolation, the Antichrist, shall appear who threatens desolation of the world. After he comes, sacrifice and drink offering, which now in every way is offered by the nations to God, shall be taken away.” (Commentary on Daniel, by Hippolytus, book 4, 35.3)
Hippolytus returned to this subject some pages later, writing:
“Just as also he spoke to Daniel, “And he shall establish a covenant with many for one week and it will be that in the half of the week he shall take away my sacrifice and drink offering,” so that the one week may be shown as divided into two, after the two witnesses will have preached for three and a half years, the Antichrist will wage war against the saints the remainder of the week and will desolate all the world so that what was spoken may be fulfilled, “And they will give the abomination of desolation one thousand two hundred ninety days. Blessed is he who endures to Christ and reaches the one thousand three hundred thirty-five days!” (Commentary on Daniel, by Hippolytus, book 4, 50.2)
THis was also taught, although not quite as clearly, by Irenaeus, in the very oldest Christian commentary on Bible prophecy (of any significant length) that has survived to the present day. This is the last twelve chapters of the very famous five volume work by Irenaeus, titled "Against Heresies." Irenaeus said:
“The Lord also spoke as follows to those who did not believe in Him: ‘I have come in my Father’s name, and ye have not received Me: when another shall come in his own name, him ye will receive,’ calling Antichrist ‘the other,’ because he is alienated from the Lord. This is also the unjust judge, whom the Lord mentioned as one ‘who feared not God, neither regarded man,’ to whom the widow fled in her forgetfulness of God,—that is, the earthly Jerusalem,—to be avenged of her adversary. Which also he shall do in the time of his kingdom: he shall remove his kingdom into that [city], and shall sit in the temple of God, leading astray those who worship him, as if he were Christ.” (Against Heresies, by Irenaeus, book V, chapter XXV, section 4)
“Moreover, he (the apostle) has also pointed out this which I have shown in many ways, that the temple in Jerusalem was made by the direction of the true God. For the apostle himself, speaking in his own person, distinctly called it the temple of God. Now I have shown in the third book, that no one is termed God by the apostles when speaking for themselves, except Him who truly is God, the Father of our Lord, by whose directions the temple which is at Jerusalem was constructed for those purposes which I have already mentioned; in which [temple] the enemy shall sit, endeavouring to show himself as Christ, as the Lord also declares: ‘But when ye shall see the abomination of desolation, which has been spoken of by Daniel the prophet, standing in the holy place (let him that readeth understand), then let those who are in Judea flee into the mountains; and he who is upon the house-top, let him not come down to take anything out of his house: for there shall then be great hardship, such as has not been from the beginning of the world until now, nor ever shall be.’” (Against Heresies, by Irenaeus, book V, chapter XXV, section 2)
“And then he points out the time that his tyranny shall last, during which the saints shall be put to flight, they who offer a pure sacrifice unto God: ‘And in the midst of the week,’ he says, ‘the sacrifice and the libation shall be taken away, and the abomination of desolation [shall be brought] into the temple: even unto the consummation of the time shall the desolation be complete.’Now three years and six months constitute the half-week.” (Against Heresies, by Irenaeus, book V, chapter XXV, section 4)
In this series of statements, we notice that in the first of them Irenaeus clearly says that the Antichrist “shall remove his kingdom into” [“the earthly Jerusalem”] “and shall sit in the temple of God, leading astray those who worship him, as if he were Christ.” In the second he insists that “the temple which is at Jerusalem” is the place “in which [temple] the enemy shall sit, endeavouring to show himself as Christ.” And then he quotes Daniel 9:27, “‘And in the midst of the week,’ he says, ‘the sacrifice and the libation shall be taken away.’” So in the last of these statements he very clearly refers to Daniel’s seventieth week as the week in which the Antichrist will come.
Thus we see in these statements of Irenaeus each of the following concepts:
1. That in the future there will again be a temple in Jerusalem.
2. That this future temple will be “the temple of God.”
3. That this future Jewish temple is where the Antichrist will sit as God.
4. And that Daniel’s seventieth week remains to be fulfilled in the future.
Each of these concepts is unquestionably an element of Dispensationalism, and is incompatible with Covenant Theology.
As a side note, we should note that the concept of calculating these weeks in accordance with Jewish years, rather than solar years, was also introduced at this time. Although Julius Africanus concluded that the seventy weeks were fulfilled, he clearly taught that they should be calculated “according to the numeration of the Jews,” saying:
“It is by calculating from Artaxerxes, therefore, up to the time of Christ that the seventy weeks are made up, according to the numeration of the Jews. For from Nehemiah, who was despatched by Artaxerxes to build Jerusalem in the 115th year of the Persian empire, and the 4th year of the 83d Olympiad, and the 20th year of the reign of Artaxerxes himself, up to ibis date, which was the second year of the 202d Olympiad, and the 16th year of the reign of Tiberius Caesar, there are reckoned 475 years, which make 490 according to the Hebrew numeration, as they measure the years by the course of the moon; so that, as is easy to show, their year consists of 354 days, while the solar year has 365¼ days. For the latter exceeds the period of twelve months, according to the moon’s course, by 11¼ days. Hence the Greeks and the Jews insert three intercalary months every 8 years. For 8 times 11¼ days makes up 3 months. Therefore 475 years make 59 periods of 8 years each, and 3 months besides. But since thus there are 3 intercalary months every 8 years, we get thus 15 years minus a few days; and these being added to the 475 years, make up in all the 70 weeks.” (Fragment 16 of “The Extant Fragments of the Five Books of the Chronography of Julius Africanus,” by Julius Africanus.)
