Arcana Coelestia #25
25. 'Spreading out the earth and stretching out the heavens' is a common expression in the Prophets when the subject is man's regeneration, as in Isaiah,
Thus said Jehovah, your Redeemer, He who formed you from the womb, I am Jehovah who makes all things, who stretches out the heavens Alone, and who spreads out the earth by Myself. Isaiah 44:24.
Also, when it is speaking of the Lord's Coming,
A bruised reed He does not break off and a smoking wick He does not quench; He brings forth judgement towards truth; that is, He neither shatters man's illusions nor stifles his desires. Instead He bends them towards truth and good. This verse in Isaiah continues,
The God Jehovah creates the heavens and stretches them out: He spreads out the earth and what comes from it: He gives breath 1 to the people upon it, and spirit to those who walk on it. Isaiah 42:3-5.
Such phrases recur several times elsewhere.

Arcana Coelestia #4010
4010. 'And he put three days' journey between himself and Jacob' means that their state was one in which they were totally set apart. This is clear from the meaning of 'putting a journey' as being set apart; from the meaning of 'three' as that which is last, completed, or the end, dealt with in 1825, 2788, and so is totally set apart; and from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3462.
