'Corner stone' in the Bible

On what are its foundations fastened? or who laid its cornerstone;

Therefore thus says the Lord GOD, Behold, I lay in Zion for a foundation a stone, a tested stone, a precious cornerstone, a sure foundation: he that believes shall not be in haste.

Out of him came forth the cornerstone, out of him the tent peg, out of him the battle bow, out of him every ruler together.

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

Therefore also it is contained in the scripture, Behold, I lay in Zion a chief cornerstone, elect, precious: and he that believes on him shall not be confounded.
