'Corner stone' in the Bible

Upon what are the foundations of it fastened? or who laid its corner stone;

Therefore thus saith the Lord GOD, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner stone, a sure foundation: he that believeth shall not make haste.

And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner-stone;

Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner-stone, elect, precious: and he that believeth on him shall not be confounded.
