Numbers 22:15-22

15Then Balak sent representatives once again, more numerous and more distinguished than 1the previous. 16They came to Balaam and said to him, “This is what Balak the son of Zippor says: ‘I beg you, let nothing keep you from coming to me; 17for I will indeed honor you richly, and I will do whatever you tell me. 2Please come then, curse this people for me.’” 18But Balaam replied to the servants of Balak, “3Even if Balak were to give me his house full of silver and gold, I could not do anything, either small or great, contrary to the 4command of the Lord my God. 19Now please, you also stay here tonight, and I will find out what else the Lord will say to me.” 20And God came to Balaam at night and said to him, “If the men have come to call you, rise and go with them; but you shall do 5only the thing that I tell you.”

216So Balaam arose in the morning, saddled his donkey, and went with the leaders of Moab. 22But God was angry that he was going, 7and the angel of the Lord took his stand in the road as an adversary against him. Now he was riding on his donkey, and his two servants were with him.
