God is in charge of everything.

Now Balak the son of Zippor saw all that Israel had done to the Amorites. And Moab was exceedingly afraid of the people because they were many, and Moab was sick with dread because of the children of Israel. Then he sent messengers to Balaam the son of Beor at Pethor, which is near the River in the land of the sons of his people, to call him, saying: “Look, a people has come from Egypt. See, they cover the face of the earth, and are settling next to me! Therefore please come at once, curse this people for me, for they are too mighty for me. Perhaps I shall be able to defeat them and drive them out of the land, for I know that he whom you bless is blessed, and he whom you curse is cursed.” So the elders of Moab and the elders of Midian departed with the diviner’s fee in their hand, and they came to Balaam and spoke to him the words of Balak. Then God came to Balaam and said, “Who are these men with you?” So Balaam said to God, “Balak the son of Zippor, king of Moab, has sent to me, saying, ‘Look, a people has come out of Egypt, and they cover the face of the earth. Come now, curse them for me; perhaps I shall be able to overpower them and drive them out.’ ” And God said to Balaam, “You shall not go with them; you shall not curse the people, for they are blessed.” So Balaam rose in the morning and said to the princes of Balak, “Go back to your land, for the Lord has refused to give me permission to go with you.”
