Numbers 22:18-20

18Balaam replied to the servants of Balak, “1Though Balak were to give me his house full of silver and gold, I could not do anything, either small or great, contrary to the 2command of the Lord my God. 19Now please, you also stay here tonight, and I will find out what else the Lord will speak to me.” 20God came to Balaam at night and said to him, “If the men have come to call you, rise up and go with them; but 3only the word which I speak to you shall you do.”
