'In Zion' in the Bible

Blow [the] trumpet in Zion, and sound the alarm on {my holy mountain}! Let all the inhabitants of the land tremble, for the day of Yahweh [is] coming --[it is] indeed near.

Blow [the] trumpet in Zion, sanctify a fast, call an assembly;

And you will know that I, Yahweh your God, [am] dwelling in Zion, my holy mountain. And Jerusalem will be [a place of] holiness, and strangers will pass through [it] no longer.

{I will cleanse their bloodguilt} [that] {I did not cleanse}, for Yahweh is dwelling in Zion.
