Rabbi Samson Raphael Hirsch Zt”l explains the meaning of “jur” (spirit) as analogous to “”jur” (wind). Just as the wind is invisible, only recognizable by its effects, so too, are the moral and spiritual agents of a human being. This active and moving force in a human being, the power of a discernment between right and wrong although invisible is reflected by its effect on the human being. Although every one possesses this invisible “spirit,” it was reflected emphatically in Yehoshua. He was a uc jur rat aht – one who possessed this spiritual quality to an eminent degree. One must be an “aht” (human being) who possesses unseen spiritual qualities; they should be manifested throughout his endeavors, as the guiding force of his spiritual leadership of Klal Yisroel. That “aht” is then transformed into a man in whom it is noticeable that there is a spiritality in him.
