What did Balak mean when he said to Bil'am that, whoever Bil'am blessed was indeed blessed ... ?
Rashi: Refer to 22:6:3:1.
Rashbam: Balak knew full well that either Bil'am was a prophet and that his power lay in prophesy, or that he was a sorcerer, 4 and he only mentioned blessing and cursing here because they assumed that his payers and his sacrifices too, would be effective.
Seforno: Which is why he Bil'am did not ask him for an eternal B'rachah for success, or at least that he should succeed in keeping Yisrael at bay.
Seforno: By mentioning his victim's sins or because he knew the exact moment when Hashem was angry (See Torah Temimah on 23:8).
From where did Balak know that whoever Bil'am blessed was blessed ... ?
