John 11:36

Now a certain man was sick, named Lazarus, of Bethany, the town of Mary and her sister Martha.

(It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.)

Therefore his sisters sent unto him, saying, Lord, behold, he whom thou lovest is sick.

When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.
