擗匈（上毗亦反又考聲云撫心也從手辟聲下勗恭反說文匈[腐-付+隹]也從包省龱聲也經文從[冉-工+又]作胸非也）。

擗匈 (The upper character is pronounced with the fanqie 毗 + 亦 [pì]. The Kaosheng also says: "To beat one's chest." It takes the hand radical [扌] and has 辟 as its phonetic component. The lower character is pronounced with the fanqie 勗 + 恭 [xiōng]. The Shuowen says: "匈 means the chest cavity." It takes an abbreviated 包 and has 龱 as its phonetic component. The sūtra text writes 胸 with [冉-工+又], which is incorrect.)
