Numbers 22:36-40

³⁶And when Balak heard that Bil'am was come, he went out to meet him unto 'Ir-Moab, which is on the border of Arnon, which is at the outmost end of the boundary.

³⁷And Balak said unto Bil'am, Did I not earnestly send unto thee to have thee called? wherefore camest thou not unto me? in truth, am I not able to honor thee?

³⁸And Bil'am said unto Balak, Lo, I am come unto thee; have I now any power whatever to speak the least? the word that God may put in my mouth, that alone must I speak.

³⁹And Bil'am went with Balak, and they came unto Kiryath-chuzoth.

⁴⁰And Balak slew oxen and sheep, and sent to Bil'am and to the princes that were with him.
