Numbers 22:18-20

18But Balaam answered and said to the servants of Balak, aThough Balak were to give me his house full of silver and gold, bI could not go beyond the command of the Lord my God to do less or more. 19So you, too, cplease stay here tonight, that I may know what more the Lord will say to me.” 20 dAnd God came to Balaam at night and said to him, “If the men have come to call you, rise, go with them; ebut only do what I tell you.”
