Famous quotes containing the words rock and/or oil:

    “Glorious things of thee are spoken, Zion city of our God!
    He, whose word cannot be broken, Form’d for thee his own abode:
    On the rock of ages founded, What can shake thy sure repose?
    With salvation’s walls surrounded Thou may’st smile at all thy foes.”
    —John Newton (1725–1807)
