Arcana Coelestia #9053
9053. 'Hand for hand' means if anything of the power of spiritual truth is injured or wiped out by them. This is clear from the meaning of 'hand' as the power that comes from truth, 3091, 3387, 4931-4937, 6292, 6947, 7188, 7189, 7518, 7673, 8050, 8153, 8281, [in particular] the power that comes from spiritual truth, 5327, 5328, 7011.
Arcana Coelestia #8050
8050. 'For by strength of hand Jehovah brought you out from there' means that they were delivered by the Lord's Divine power. This is clear from the meaning of 'strength of hand' as power or, when used in reference to Jehovah, as almighty power (the fact that 'strength' means power is self-evident; and the fact that 'hand' likewise means power, see 878, 3387, 4931-4937, 5327, 5328, 5544, 6947, 7188, 7189, 7518, 7673); and from the meaning of 'bringing out' as delivering. That 'Jehovah' is the Lord, see above in 8046.
