'Holy Hill' in the Bible

But I have put my king on my holy hill of Zion.

Lord, who may have a resting-place in your tent, a living-place on your holy hill?

O send out your light and your true word; let them be my guide: let them take me to your holy hill, and to your tents.

Give high honour to the Lord our God, worshipping with your faces turned to his holy hill; for the Lord our God is holy.
