Parshas Bolok
And (Bilaam) said to them (the Elders of Midyon and the Elders of Moav), stay the night, and I’ll give you an answer, as Hashem speaks to me. And the officers of Moav stayed with Bilaam’. The Gemorah in Sanhedrin דף ק’’ה . asks why the Posuk only mentions that the Elders of Moav stayed the night, but not the Elders of Midyon? The Gemorah explains, that once Bilaam explained that he was only able to curse Klal Yisroel with the approval of Hashem, they realised it was a lost cause, as ‘A Father would never hate his son’.
