Numbers 23:11

I took thee to curse. There was no deceit or subterfuge on Balak’s part. He did not understand that Balaam had been permitted to come only on condition that he speak the words God would put in his mouth. Of course he had told Balak as much (ch. 22:38), but, like Balaam, who should have known better, the king no doubt thought God could be persuaded to change His mind. Balaam’s arrival made it appear to Balak that the prophet himself thought this possible.

Blessed them altogether. The Hebrew is very emphatic: “blessing thou hast blessed.” Balaam had not merely refrained from cursing Israel; he positively blessed them.
