John 11:8-10

8The disciples said to Him, “Rabbi (Teacher), the Jews were only recently going to stone You, and You are [thinking of] going back there again?”

9Jesus answered, “Are there not twelve hours [of light] in the day? Anyone who walks in the daytime does not stumble, because he sees [by] the light of this world.

10But if anyone walks in the night, he stumbles, because there is no light in him.”
