Arcana Coelestia # 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.
Ezekiel 25:16
16
therefore thus says the Lord Yahweh, Behold, I will stretch out my hand on the Philistines, and I will cut off the Cherethites, and destroy the remnant of the sea coast.
