Psalm 118:22

New International Version (NIV)

22 The stone the builders rejected
has become the cornerstone;

[editor-surveyor]

>> “The stone the builders rejected
has become the cornerstone” <<

.
Other versions have that more accurately as “the head of the corner” in reference to the stone that finishes the pyramid, at the vertex. I.e. Christ finished the job of saving the elect.
