'Stone' in the Bible

For behold, the stone that I have laid before Joshua upon one stone are seven eyes; behold, I will engrave the graving thereof, saith Jehovah of hosts, and I will remove the iniquity of this land in one day.

And it shall come to pass in that day that I will make Jerusalem a burdensome stone unto all peoples: all that burden themselves with it shall certainly be wounded, and all the nations of the earth shall be assembled together against it.
