According to the text, why is temple mount important to jews?

The Temple Mount is the holiest site in Judaism, the third holiest site in Islam, and a revered site to Christians. To the Jews it is known as Har HaMoriyah (“Mount Moriah”) and Har HaBayit (“Temple Mount”); to Muslims it is known as Haram el Sharif (“the Sacred Noble Sanctuary”). In the Bible it is also called Mount Zion (Psalm 48:2; Isaiah 4:5). Because of its importance to three major religions, its ownership has been hotly contested for nearly two thousand years. Today the Temple Mount is under the control of the Jerusalem Islamic Waqf, a trust that was established in 1187 to manage the Islamic structures in Jerusalem. Under their current rules, access to the holy sites is prohibited to all non-Muslims.
