《逸周书·卷八·职方解》
天子将巡视境内，就先向四方发布戒备命令，说道： 各自整治你们的邦国，考察你们的职责，不可不认真戒备。因为国家有大刑。 
王将巡狩，则戒于四方，曰各修平乃守，考乃职事，无敢不敬戒，国有大刑。
Emperor will inspect territory, first of all issue a warning to all sides, say: sort out your country, investigate your duties, you cannot not be serious about warning. Because country has a big punishment.
