Why does Balaam say Χ”' ΧΧœΧ•Χ§Χ™ here and not in other places?

Did Balak's messengers see/hear the miracle of Balaam's donkey and the malach?

Why did Hashem convey His message through a donkey, one of the special creations on the first Erev Shabbos? Why did Hashem choose Balaam, who was evil?

"ΧžΧ™ ΧžΧ Χ” Χ’Χ€Χ¨ Χ™Χ’Χ§Χ‘"
