5.22

沃朕（上烏穀反尚書曰啟乃心沃朕心賈注國語云沃美也廣雅曰沃清也說文沃溉灌也下朕字尒雅曰朕予言我也案古者貴賤同稱自秦始皇唯天子獨稱朕也）。

Moisten my [heart] (沃朕: the first character is pronounced *wu* + *gu* [= *wò*]; the *Shangshu* says: "Open your heart to moisten my heart"; Jia's commentary on the *Guoyu* says *wo* means to enrich or beautify; the *Guangya* says *wo* means clear; the *Shuowen jiezi* says *wo* means to irrigate; the second character, *zhen*, the *Erya* says *zhen* means 'I' or 'me'; note that in antiquity the noble and base used it alike, but from the First Emperor of Qin onward, only the Son of Heaven alone referred to himself as *zhen*).
