'Holy City' in the Bible

And the rulers of the people dwelt at Jerusalem: the rest of the people also cast lots, to bring one of ten to dwell in Jerusalem the holy city, and nine tenths to dwell in other cities.

All the Levites in the holy city were two hundred fourscore and four.

For they call themselves after the holy city, and anchor themselves upon the God of Israel; The LORD of hosts is his name.

Awake, awake; put on your strength, O Zion; put on your beautiful garments, O Jerusalem, the holy city: for no longer, there shall no more come into you the uncircumcised and the unclean.

Seventy weeks are determined upon your people and upon your holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
