'Mount' in the Bible

And the young man that told him said, I happened by chance to be upon mount Gilboa, and behold, Saul leaned on his spear; and behold, the chariots and horsemen followed hard after him.

The matter is not so; but a man of mount Ephraim, Sheba the son of Bichri by name, has lifted up his hand against the king, against David: give up him only, and I will depart from the city. And the woman said to Joab, Behold, his head shall be thrown to thee over the wall.
