[The Posuk in Parshas Bolok quotes Bilaam’s prophecy,] “I will advise you what this nation [the Jews] will do to your nation [the Moabites] at the end of days [באחרית הימים] (Bamidbar 24:10). This refers to the end of the days of Yomtov which is Simchas Torah. Then, due to our great aveiros, the Satan will rule and do almost exactly what Bilaam had advised. There would be a mixture of men and women, young men and young women, dancing like rams and goats, and foxes will dance there. And this, due to our numerous sins, will make a great gap, losing all of the good they merited during Days of Awe like these. Woe, Bilaam’s advice that will be done in the end of days.
The idea is not to Chas V’Shalom place blame on anyone, but to see how careful we need to be as a nation in our Holy Land.
When seeing something like this I believe it is always important to 1) See if it’s real and 2) to read the context before and after it.
