Prayer and Windows: Thoughts for Parashat Noah
God’s instructions to Noah for building the ark include: “A light you shall make to the ark,” (Bereishith 6:16). Rashi, drawing on rabbinic tradition, offers two explanations of what this “light” was. 1) it was a window; 2) it was a precious stone.
A window provides direct light from the sun; a person inside the ark could see the skies above. A precious stone refracts light; a person inside the ark has light, but has no direct contact with the outside world.
