'Holy City' in the Bible

Now the commanders of the people lived in Jerusalem, but the remainder of the people cast lots to bring one out of ten to live in the holy city of Jerusalem, the [other] nine's place [was in] the [other] cities.

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

For they call themselves {after the holy city}, and they lean on the God of Israel-- Yahweh of hosts [is] his name.

Awake! Awake; put on your strength, Zion! Put on the garments of your beauty, Jerusalem, {holy city}! For [the] uncircumcised and [the] unclean shall not {continue to} enter you any longer.

"Seventy weeks is decreed for your people and {for your holy city}, to put an end to the transgression and to seal [up] sin and to make atonement for guilt and to bring [in] everlasting righteousness and to seal vision and prophet and to anoint {the most holy place}.
