John 11:7-10

7 After the two days, he said to his disciples, "Let's go back to Judea."

8 They said, "Rabbi, you can't do that. The Jews are out to kill you, and you're going back?"

9 Jesus replied, "Are there not twelve hours of daylight? Anyone who walks in daylight doesn't stumble because there's plenty of light from the sun.

10 Walking at night, he might very well stumble because he can't see where he's going."
