Arcana Coelestia #3
3. Without such life the Word as regards the letter is dead, for it is the same with the Word as it is with man, who, as the Christian world knows, is internal as well as external. The external man if parted from the internal man is just a body and therefore dead. It is the internal man which lives and imparts life to the external. The internal man is the soul of the external man. The same applies to the Word which as to the letter alone is like the body without a soul.
Isaiah 48:20-21
20
Go forth from Babylon, flee from the Chaldeans; with a voice of singing declare, tell this, utter it even to the end of the earth: say, Yahweh has redeemed his servant Jacob.
21
They didn't thirst when he led them through the deserts; he caused the waters to flow out of the rock for them; he split the rock also, and the waters gushed out.
