'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 Yahweh comes, for it is close at hand:

Blow the trumpet in Zion! Sanctify a fast. Call a solemn assembly.

"So you will know that I am Yahweh, your God, dwelling in Zion, my holy mountain. Then Jerusalem will be holy, and no strangers will pass through her any more.

I will cleanse their blood, that I have not cleansed: for Yahweh dwells in Zion."
