Balak ♂, was a king of the Moabites.
During the time when the Israelites camed across the river of the Moabites, Balak was their king. Because the people of Moab were terrified, Balak sent for Balaam ordering him to curse the Israelites. When the first delegation was with Balaam, God did not allow him to go. When the second delegation was there, God allowed him to go with the Moabites. But God warned him only to say the words that God would put in his mouth.
When Balaam had finally arrived at Balak's place, they went to Kiriath Huzoth. There Balak sacrificed cattle and sheep. The next morning, they went to Bamoth Baal from where they saw a part of the people of Israel. They built seven altars and offered a bull and a ram on each. Balaam then talked with God and blessed the people of Israel.
Disturbed by this, Balak brought Balaam to the field of Zophim on top of Pisgah. They built seven altars and offered a bull and a ram on each, again. Another time Balaam talked with God and then tolk Balak, that God would not change his opinion.
So Balak brought Balaam to the top of Peor, hoping that Balaam would curse the Israelites there. Again they built seven altars and offered a bull and a ram on each.
