'Mount' in the Bible

Blow the trumpet in Zion [warning of impending judgment],Sound an alarm on My holy mountain [Zion]!Let all the inhabitants of the land tremble and shudder in fear,For the [judgment] day of the Lord is coming;It is close at hand,

And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the LORD hath said, and in the remnant whom the LORD shall call.
