The fourth NINE, undivided, shows one from whose buttocks the skin has been stripped, and who walks slowly and with difficulty. (If he could act) like. a sheep led (after its companions), occasion for repentance would disappear. But though he hear these words, he will not believe them.
'He walks slowly and with difficulty:' - he is not in the place appropriate to him. 'He hears these words, but does not believe them:' - he hears, but does not understand.
