'Holy City' in the Bible

And the rulers of the people lived at Jerusalem. And the rest of the people cast lots, to bring one of every ten to live in Jerusalem, the holy city, and nine parts in other cities.

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

For they call themselves of the holy city, and rest themselves on the God of Israel; Jehovah of Hosts is His name.

Awake! Awake! Put on your strength, Zion; put on your beautiful robes, O Jerusalem, the holy city. For never again shall come to you uncircumcised and unclean ones.

Seventy weeks are decreed as to your people and as to your holy city, to finish the transgression and to make an end of sins, and to make atonement for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the Most Holy.
