Numbers 22:7-8

22:7 So the elders of Moab and the elders of Midian departed with the fee for divination in their hand. They came to Balaam and reported to him the words of Balak. 22:8 He replied to them, “Stay here tonight, and I will bring back to you whatever word the Lord may speak to me.” So the princes of Moab stayed with Balaam.
