'Holy Hill' in the Bible

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

I cried unto the LORD with my voice, and he heard me out of his holy hill. Selah.

{A Psalm of David.} LORD, who shall abide 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 unto thy holy hill, and to thy tabernacles.

Exalt the LORD our God, and worship at his holy hill; for the LORD our God is holy.
