Arcana Coelestia #4934
4934. I have seen a bare arm, bent forwards, possessing so much strength and at the same time rousing so much terror that I not only shuddered at the sight of it but also felt as though I could be entirely smashed to pieces by it. It was irresistible. I have seen this arm on two occasions, and from this I was led to realize that 'the arms' means strength and 'the hands' power. I also felt the heat radiating from this arm.
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.
