'In Zion' in the Bible

Blow ye the trumpet in Zion, and sound an alarm in my holy mountain. Let all the inhabitants of the land tremble. For the day of LORD comes, for it is near at hand,

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

So ye shall know that I am LORD your God, dwelling in Zion my holy mountain. Then Jerusalem shall be holy, and no strangers shall pass through her any more.

And I will cleanse their blood, that I have not cleansed. For LORD dwells in Zion.
