'In Zion' in the Bible

Blow a ram's horn in Zion, and sound an alarm in My holy mountain; let all the inhabitants of the land tremble. For the day of Jehovah comes, for it is near at hand;

Blow a trumpet in Zion, sanctify a fast, call a solemn gathering.

So you shall know that I am Jehovah your God dwelling in Zion, My holy mountain. And Jerusalem shall be a holy thing, and no aliens shall pass through her any more.

And I will cleanse their blood which I did not cleanse; and Jehovah is dwelling in Zion.
