'In Zion' in the Bible

Blow a 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;Surely it is near,

Blow a trumpet in Zion,Consecrate a fast, proclaim a solemn assembly,

Then you will know that I am the Lord your God,Dwelling in Zion, My holy mountain.So Jerusalem will be holy,And strangers will pass through it no more.

And I will avenge their blood which I have not avenged,For the Lord dwells in Zion.
