John 11:5 (KJV)

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.

When he had heard therefore that he was sick, he abode two days still in the same place where he was.

Then after that saith he to his disciples, Let us go into Judaea again.

His disciples say unto him, Master, the Jews of late sought to stone thee; and goest thou thither again?

Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world.

But if a man walk in the night, he stumbleth, because there is no light in him.
