Moshe removes the frogs, but Pharaoh still refuses to release the Jews. Then Moshe tells Aaron to bring the plague of lice, the magicians are not able to duplicate the plague but Pharaoh still refuses to release the Jews. Moshe then brings the fourth plague of wild animals. Pharaoh says that he will allow the Jews to go sacrifice to their G-d but after the plague ends he reneges.
