'In Zion' in the Bible

Blow the horn in Zion;sound the alarm on My holy mountain!Let all the residents of the land tremble,for the Day of the Lord is coming;in fact, it is near—

Blow the horn in Zion!Announce a sacred fast;proclaim an assembly.

Then you will knowthat I am Yahweh your God,who dwells in Zion, My holy mountain.Jerusalem will be holy,and foreigners will never overrun it again.

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