9638.“一块板必有两榫”表来自它的能力，也就是说，通过真理来自良善的能力。这从“榫”的含义清楚可知，“榫”（hands，即手）是指能力（参看878，3387，4931-4937，5327，5328，6292，6947，7011，7188，7189，7518，7673，8050，8153，8281，9133节），一切能力皆通过真理从良善而来（参看6344，6423，9327，9410节）。
Potts(1905-1910) 9638
9638. Two hands shall there be in one plank. That this signifies power from it, namely, through truth from good, is evident from the signification of "hands," as being power (see n. 878, 3387, 4931-4937, 5327, 5328, 6292, 6947, 7011, 7188, 7189, 7518, 7673, 8050, 8153, 8281, 9133; and that all power is through truth from good, n. 6344, 6423, 9327, 9410).
Elliott(1983-1999) 9638
9638. 'There shall be two hands to one board' means the power from it, that is to say, through truth from good. This is clear from the meaning of 'hands' or 'tenons' as power, dealt with in 878, 3387, 4931-4937, 5327, 5328, 6292, 6947, 7011, 7188, 7189, 7518, 7673, 8050, 8153, 8281, 9133; and all power comes through truth from good, 6344, 6423, 9327, 9410.
