Arcana Coelestia#6086
6086. 'And if you know that there are among them men with energy' means the more outstanding contents of doctrine. This is clear from the meaning of 'men with energy' a, the more outstanding contents of doctrine. For 'man' means one who has intelligence and also means truth, 158, 265, 749, 1007, 3174, 4823, and as a consequence means doctrine, while 'energetic' means what is outstanding In the original language 'energy' is expressed by a word that also means strength and power, which in the internal sense means those things that prevail and so are more outstanding.
Arcana Coelestia#158
158. That 'man' (vir) means the internal man, or what amounts to the same, one who is intelligent and wise, is clear in Isaiah,
I look, and there is no man, and from these there is no counsellor. Isaiah 41:18.
['No man'] stands for no wise and intelligent person. In Jeremiah,
Run to and fro through the streets of Jerusalem and see if you find a man, if anyone is executing judgement and seeking truth. Jeremiah 5:1.
'Executing judgement' stands for being wise, and 'seeking truth' for having intelligence.
