Mountains of the Lord

Who may ascend the mountain of the Lord? Who may stand in His holy place?
The one who has clean hands and a pure heart, who does not trust in an idol
    or swear by a false god.  Psalms 24:3-4

"Faith to move mountains has been assigned to you."
I lift up my eyes to the mountains—where does my help come from?  My help comes from the Lord, the Maker of heaven and earth.  Psalms 121:6
