'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 your tabernacle? who shall dwell in your holy hill?

O send out your light and your truth: let them lead me; let them bring me unto your holy hill, and to your tabernacles.

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