R. Yose said: All my life I have been perplexed by the verse "And thou shalt grope at noonday as the blind gropeth in darkness" (Deut. 28:29). What difference [I asked], does it make to a blind man whether it be dark or light? [Nor did I find the answer] until the following incident occurred. I was once walking at the darkest time of the night when I saw a blind man walking on the road with a torch in his hand. I said to him, "My son, what need have you for this torch?" He replied, "As long as I have this torch in my hand, people see me and save me from holes, thorns, and briers."This suggests how important being seen is. Today, when driving at night we are often dependent on those walking or biking be visible. The same is true of drivers, if you are driving a car at night without the headlights on, you risk being hit by another car or hitting a biker or pedestrian or biker. The blind man depends on others seeing him to get necessary help. All of us are blind in some way and when and if we allow others to realize it, they can help us.
