'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 Jehovah cometh, for it is at hand;

Blow the trumpet in Zion, hallow a fast, proclaim a solemn assembly;

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

And I will purge them from the blood from which I had not purged them: for Jehovah dwelleth in Zion.
