《史记·三十世家·晋世家》
成王说： 晋侯在外逃亡十九年，受困的时间太久了，终于返回晋国。他因尝尽了艰难险阻，因此能善待他的百姓，上天庇佑他，他不可阻挡。 
王曰： 晋侯亡在外十九年，困日久矣，果得反国，险厄尽知之，能用其民，天之所开，不可当。 
King Cheng said: "The Marquis of Jin has lived in exile for nineteen years. He has been in distress for too long, and he has finally returned to Jin. His hardships have made him treat his people well, and he is blessed by heaven. He is unstoppable!"
