29.19

持駛水（駛音使去聲字也蒼頡篇云駛疾也水流速也急也古今正字從馬史聲經從夬非也）。

Restrain the swift water 持駛水 (The character shi 駛 is pronounced shi, in the falling tone; the Cang Jie pian says: “駛 means swift; the current is fast; urgent.” The Gujin zhengzi derives it from ma 馬 [horse] with the phonetic shi 史; the sūtra wrote it with kuai 夬, which is incorrect).
