“These things I have spoken to you so that you may be kept from stumbling.

But Jesus, conscious that His disciples grumbled at this, said to them, “Does this cause you to stumble?

Jesus answered, “Are there not twelve hours in the day? If anyone walks in the day, he does not stumble, because he sees the light of this world.

But if anyone walks in the night, he stumbles, because the light is not in him.”
