Numbers 22:36-40

And when Balak heard that Balaam was come, he went out to meet him unto a city of Moab, which is in the border of Arnon, which is in the utmost coast.

And Balak said unto Balaam, Did I not earnestly send unto thee to call thee? wherefore camest thou not unto me? am I not able indeed to promote thee to honour?

And Balaam said unto Balak, Lo, I am come unto thee: have I now any power at all to say any thing? the word that God putteth in my mouth, that shall I speak.

And Balaam went with Balak, and they came unto Kirjath-huzoth.

And Balak offered oxen and sheep, and sent to Balaam, and to the princes that were with him.
