《左传·定公·定公四年》
随国人为交出子期占卜吉凶，不吉利，就辞谢吴国说： 以随国的偏僻狭小而紧挨着楚国，楚国确实保全了我们。随、楚世世代代都有盟誓，到今天没有改变。
随人卜与之，不吉。乃辞吴曰： 以随之辟小而密迩于楚，楚实存之，世有盟誓，至于今未改。
Sui consulted the oracle bones to see whether they should hand Zi Qi over or not. The response was unfavorable, so they curtly rejected Wu's request, saying, "Sui is small and remote, and yet it borders on Chu. It is true that Chu has always protected us. Sui and Chu have made an alliance that goes back generations, and it remains in force to this day."
