《礼记·大学》
看到贤人而不举荐，举荐了但不尽快使用，这是怠慢。看到不好的人却不能摈弃，摈弃了却不能放逐到远方，这是过错。
见贤而不能举，举而不能先，命也；见不善而不能退，退而不能远，过也。
Seeing the wise but not recommending them, or recommending them but not using them as soon as possible, is negligence. Seeing bad people but not being able to abandon them, abandoning them but not banishing them to distant places, is a mistake.
