一切經音義 6.12

6.12

四雙（朔牎反顧野王曰雙猶兩也方言云二飛鳥也說文二枚也從二隹隹鳥也從文文手也手持二鳥曰雙經從反作雙非也）。

四雙 ("four pairs": [fanqie] 朔牎 [shuāng]. Gu Yewang says: "Shuāng is like two." Fangyan says: "Two flying birds." Shuowen says: "Two units." It is composed of two 隹—隹 means bird—and 又; 又 means a hand. A hand holding two birds is called shuāng. In the scripture text it is written with a reversed component as 雙, which is incorrect.)
