In John 9:4, Jesus also uses 'day' and 'night' to describe his limited time for doing the Father's work, reinforcing the urgency of walking in the light.

In John 12:35, Jesus warns 'walk while you have the light' before darkness comes, directly echoing the day/night metaphor here.

In Luke 13:31-33, Jesus insists he must continue his work 'today and tomorrow' despite threats, mirroring the fixed 'twelve hours' of opportunity.

In Isaiah 59:10, people stumble even at noonday because of sin — a direct contrast to the promise of not stumbling in the light.
