'Summon' in the Bible

At that time, Zippor's son Balak was the king of Moab. He sent messengers to Beor's son Balaam in Pethor, near the Euphrates River, the land where the descendants of his people originated, to summon his aid. He said, "Look! A group of people have escaped from Egypt. They cover the surface of the whole earth, and are sitting here right in front of me.

Balak asked Balaam, "Didn't I repeatedly send for you to summon you? Why didn't you come to me? I can pay you well, can't I?"
