Charles Ellicott Commentary Numbers 22:14

"And the princes of Moab rose up, and they went unto Balak, and said, Balaam refuseth to come with us." — Numbers 22:14 (ASV)

Balaam refuses to come with us. It does not appear that Balaam had told the messengers of Balak the ground of the Divine prohibition; namely, for they are blessed. Balak accordingly entertained the hope that stronger inducements would prevail with Balaam.
