'Holy City' in the Bible

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

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

(for they call themselves of 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, O Jerusalem, the holy city: for henceforth there shall no more come into thee the uncircumcised and the unclean.

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