'In Zion' in the Bible

Blow the trumpet in Zion, and sound an alarm on my holy mountain. Let all the inhabitants of the land tremble, for the day of the LORD is coming, for it is near.

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

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

And I will pardon their bloodguilt, which I have not pardoned, for the LORD dwells in Zion."
