Numbers 22:2-6

2Now Balak the son of Zippor saw all that Israel had done to the Amorites.

3And Moab was exceedingly afraid of the people because they were many, and Moab was sick with dread because of the children of Israel.

4So Moab said to the elders of Midian, “Now this company will lick up everything around us, as an ox licks up the grass of the field.” And Balak the son of Zippor was king of the Moabites at that time.

5Then 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!

6Therefore 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.”
