'In Zion' in the Bible

Blow the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD comes, for it is near at hand;

Blow the trumpet in Zion, sanctify a fast, call a solemn assembly:

So shall you know that I am the LORD your God dwelling in Zion, my holy mountain: then shall Jerusalem be holy, and there shall no strangers pass through her any more.

For I will cleanse their blood that I have not cleansed: for the LORD dwells in Zion.
