《史记·三十世家·孔子世家》
孔子知道弟子们心中不高兴。便叫来子路问道： 《诗经》上说 不是犀牛也不是老虎，然而它却排徊在旷野上 ，难道是我们奉行的道义不对吗？
孔子知弟子有愠心，乃召子路而问曰： 诗云 匪兕匪虎，率彼旷野 。吾道非邪？
Confucius saw that his disciples had unhappy expressions on their faces. He called out to Zi Lu and said, “In the Book of Songs it says, ‘It is neither a rhinoceros nor a tiger, Yet it roams the wilderness.’ Is it because our ways are not right?”
