Shem Mishmuel brings a Rashi which discusses the unusual loshen — regalim (the word usually used to denote festivals) used in our Parsha Balak where Hashem brings the donkey to speak to Bila’am expressing; “What have I done to you, that you hit me these three times.” [1]
Shem Mishmuel brings Rashi quoting Chazal which notes: “These three times — it was a hint that he [Bila’am] wanted to uproot the Jewish nation, who celebrate three pilgrim festivals each year.” [2]
