'Hill of the Lord' in the Bible

Let seven men of his family be given up to us and we will put an end to them by hanging them before the Lord in Gibeon, on the hill of the Lord. And the king said, I will give them.

He took away the strange gods and the image out of the house of the Lord, and all the altars he had put up on the hill of the Lord's house and in Jerusalem, and put them out of the town.
