Numbers 22:37-38

37Balak said to Balaam, ‘You should have come the first time that I sent men to get you. Why did you not come? Did you think that I could not pay you with enough good things?’

38Balaam said to Balak, ‘Anyway, I have come to you now! But I cannot choose to say anything. I can only say the words that God tells me to speak.’
