'Stone' in the Bible

To whom coming, a living stone, cast away indeed as worthless by men, but with God chosen, precious,

To you therefore who believe is the preciousness; but to the disobedient, the stone which the builders cast away as worthless, this is become head of the corner,

and a stone of stumbling and rock of offence; who stumble at the word, being disobedient to which also they have been appointed.
