Numbers 22:8-14

8And he said to them, "Lodge here tonight, and I will bring back word to you, as the Lord speaks to me." So the princes of Moab stayed with Balaam.

9And God came to Balaam and said, "Who are these men with you?"

10And Balaam said to God, "Balak the son of Zippor, king of Moab, has sent to me, saying,

11'Behold, a people has come out of Egypt, and it covers the face of the earth. Now come, curse them for me. Perhaps I shall be able to fight against them and drive them out.'"

12God said to Balaam, "You shall not go with them. You shall not curse the people, for they are blessed."

13So Balaam rose in the morning and said to the princes of Balak, "Go to your own land, for the Lord has refused to let me go with you."

14So the princes of Moab rose and went to Balak and said, "Balaam refuses to come with us."
