מדרש על דניאל 10:20

"and there was no strange god against them": None of the nations will be permitted to come and rule over you, as it is written (Daniel 10:20) "Then I will depart. And, behold, the (tutelary) power of Greece approaches" (Ibid. 10) "But the power of Persia stood opposed to me," (Ibid. 21) "But I will tell you what is inscribed in truthful writing, etc."
