"מזמור שיר ליום השבת, טוב להודות לד'..."
"The place of the eye is arranged on the highest position of the body, together with the other sense organs, in order to see and perceive from afar. It is safely recessed in a protruding bone frame, which protects it from blows. It is furnished with a lid, which rolls down automatically whenever an object approaches; and which rolls up conveniently out of sight when not in use."
The Marvelous Wonders of Creation, by Rabbi Mordechai Menachem Reich ZT"L (Mordechai Menachem Mendel -en Dovid Aryeh), adapted from the works of Rabbi Avigdor Miller, ZT'''L
