Numbers 22:13

And Balaam rose up in the morning and said unto the princes of Balak, Get you into your land; for the Lord refuseth to give me leave to go with you. This was a cunning way of putting it, for it withheld that part of God's message which might have broken off the negotiations definitely, and at the same time conveyed to the messengers of Balak the feeling of Balaam that personally he was not at all disinclined to come. The men undoubtedly understood the position and the inclination of Balaam, as the sequel shows.
