'Stone of Stumbling' in the Bible

And why? Because they sought it not by faith, but as if by works of law: for they stumbled against that stone of stumbling,

as it is written: Behold, I lay in Zion a stone of stumbling, and a rock of offense: and whoever believes on him, shall not be ashamed.

and a stone of stumbling, and a rock of offense to the disobedient, who stumble at the word because they are disobedient, to which stumbling they were also appointed.
