Some questions have been raised about the source of the Rabbinic Curse on Daniel 9 as quoted in our article The 70-Week Prophecy, and by Professor Veith in his video Just Another Man. Although we have not been able to locate the exact source used in his presentation, we do offer here three sources that show the existence of such a curse:

Quote 1
A Sage said: "May the curse of heaven fall upon those who calculate the date of the advent of the Messiah, and thus create political and social unrest among the people." Sanhedrin, 97b.

Quote 2
What is meant by 'but at the end it shall speak [we-yafeah] and not lie?' — R. Samuel b. Nahmani said in the name of R. Jonathan: Blasted be¹⁸ the bones of those who calculate the end.¹⁹ For they would say, since the predetermined time has arrived, and yet he has not come, he will never come. But [even so], wait for him, as it is written, Though he tarry, wait for him. Should you say, We look forward [to his coming] but He does not: therefore Scripture saith, And therefore will the Lord wait, that he may be gracious unto you, and therefore will he be exalted, that he may have mercy upon you.²⁰ But since we look forward to it, and He does likewise, what delays [his coming]? — The Attribute of Justice delays it.²¹ But since the Attribute of Justice delays it, why do we await it? — To be rewarded [for hoping], as it is written, blessed are all they that wait for him.

Footnotes to the above:

18 [H] The verse is rendered, 'he will blast him who calculated the end.'
19 I.e., Messiah’s advent.
20 Isa. XXX, 18.
21 I.e., because we are not yet worthy of it.
22 Ibid.

Quote 4
6. Furthermore, this passage deals primarily with Jesus — not with some “future Fuehrer,” to use Hal Lindsey’s term for the Antichrist. In fact, the prophecy points so unmistakably to the time of the MESSIAH’S COMING, and so directly foretold HIS DEATH, that in later centuries Jewish rabbis who did not accept Jesus DISCOURAGED its study and finally pronounced a CURSE on all who attempt to compute the time elements! ³¹
