'Hilltop' in the Bible

So Joshua did as Moses said, and fought with Amalek; and Moses, Aaron, and Hur went up to the hilltop.

Then the king sent to Elijah a captain of fifty with his fifty [fighting men to seize the prophet]. And he went up to him, and behold, he was sitting on the top of a hill. And the captain said to him, “Man of God, the king says, ‘Come down.’”
