'Holy City' in the Bible

And the princes of the people dwelt in Jerusalem; and the rest of the people cast lots, to bring one of ten to dwell in Jerusalem, the holy city, and nine parts in the cities.

all the Levites in the holy city were two hundred and eighty-four.

For they are named after the holy city, and stay themselves upon the God of Israel: Jehovah of hosts is his name.

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

Seventy weeks are apportioned out upon thy people and upon thy holy city, to close the transgression, and to make an end of sins, and to make expiation for iniquity, and to bring in the righteousness of the ages, and to seal the vision and prophet, and to anoint the holy of holies.
