'Holy Hill' in the Bible

Yet I have set my king upon my holy hill of Zion.

I cry to LORD with my voice, and he answers me out of his holy hill. Selah.

LORD, who shall sojourn in thy tabernacle? Who shall dwell in thy holy hill?

O send out thy light and thy truth. Let them lead me. Let them bring me to thy holy hill, and to thy tabernacles.

Exalt ye LORD our God, and worship at his holy hill. For LORD our God is holy.
