Numbers 22:16
'for I will surely do you great honor, and all that you say to me I will do; come, curse this people for me' — Balak offers unprecedented honor (yaquim otcha mead meod) and unrestricted material reward. The phrase 'all that you say to me I will do' suggests Balak will fulfill any demand Balaam makes. The offer is extravagant; Balak is desperate enough to promise the moon.
