'Mount' in the Bible

And when they drew nigh unto Jerusalem, and came unto Bethphage, unto the mount of Olives, then Jesus sent two disciples,

And as he sat on the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what'shall be the sign of thy coming, and of the end of the world?

And when they had sung a hymn, they went out unto the mount of Olives.
