'Stone' in the Bible

And Tobiah the Ammonite is by him and saith, 'Also, that which they are building -- if a fox doth go up, then it hath broken down their stone wall.'

And the sea Thou hast cleaved before them, and they pass over into the midst of the sea on the dry land, and their pursuers Thou hast cast into the depths, as a stone, into the strong waters.
