'Mount' in the Bible

And when they drew near to Jerusalem and came to Bethphage, at the mount of Olives, then Jesus sent two disciples,

And as he was sitting upon the mount of Olives the disciples came to him privately, saying, Tell us, when shall these things be, and what is the sign of thy coming and the completion of the age?

And having sung a hymn, they went out to the mount of Olives.
