'Stone' in the Bible

In his tent will be seen that which is not his, burning stone is dropped on his house.

Iron is taken out of the earth, and stone is changed into brass by the fire.

On what were its pillars based, or who put down its angle-stone,

The waters are joined together, hard as a stone, and the face of the deep is covered.

His heart is as strong as a stone, hard as the lower crushing-stone.
