Arcana Coelestia #9819
9819. 'And they shall make Aaron's garments' means through whom the spiritual kingdom exists. This is clear from the meaning of 'Aaron's garments' as a representative sign of the Lord's spiritual kingdom lying adjacent to His celestial kingdom, dealt with above in 9814. The reason why the wise at heart, filled with the spirit of wisdom, were to make those garments is that by these people those in the celestial kingdom are meant, and the spiritual kingdom is what springs from and so what covers that celestial kingdom like a garment next to the body, as also becomes clear from the things that have been stated in 9818.
Ezekiel 37:9-10
9
Then he said to me, Prophesy to the wind, prophesy, son of man, and tell the wind, Thus says the Lord Yahweh: Come from the four winds, breath, and breathe on these slain, that they may live.
10
So I prophesied as he commanded me, and the breath came into them, and they lived, and stood up on their feet, an exceedingly great army.
