'In Zion' in the Bible

It will come to pass that he who is left in Zion and remains in Jerusalem will be called holy (set apart for God)—everyone who is recorded for [eternal] life in Jerusalem.

Therefore, the Lord God of hosts says this, “O My people who dwell in Zion, do not be afraid of the Assyrian who strikes you with a rod and lifts up his staff against you, as [the king of] Egypt did.

Therefore the Lord God says this,“Listen carefully, I am laying in Zion a Stone, a tested Stone,A precious Cornerstone for the [secure] foundation, firmly placed.He who believes [who trusts in, relies on, and adheres to that Stone] will not be disturbed or give way [in sudden panic].

O people in Zion, inhabitant in Jerusalem, you will weep no longer. He will most certainly be gracious to you at the sound of your cry for help; when He hears it, He will answer you.

“His rock [his stronghold] will pass away because of panic,And his princes will be terrified at the [sight of the battle] standard,”Declares the Lord, whose fire is in Zion and whose furnace is in Jerusalem.

The sinners in Zion are terrified;Trembling has seized the godless.[They cry] “Who among us can live with the consuming fire?Who among us can live with everlasting burning?”

“I bring near My righteousness [in the salvation of Israel], it is not far away;And My salvation will not delay.And I will grant salvation in Zion,And My glory for Israel.

To grant to those who mourn in Zion the following:To give them a turban instead of dust [on their heads, a sign of mourning],The oil of joy instead of mourning,The garment [expressive] of praise instead of a disheartened spirit.So they will be called the trees of righteousness [strong and magnificent, distinguished for integrity, justice, and right standing with God],The planting of the Lord, that He may be glorified.
