John 11:7-10

7 Then after this he saith to the disciples, Let us go into Judaea again.

8 The disciples say unto him, Rabbi, the Jews were but now seeking to stone thee; and goest thou thither again?

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

10 But if a man walk in the night, he stumbleth, because the light is not in him.
