'Stone' in the Bible

For lo, the stone that I put before Joshua, On one stone are seven eyes, Lo, I am graving its graving, An affirmation of Jehovah of Hosts, And I have removed the iniquity of that land in one day.

And it hath come to pass, in that day, I make Jerusalem a burdensome stone to all the peoples, All loading it are completely pressed down, And gathered against it have been all nations of the earth.
