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 #6526
6526. 'And the whole house of Joseph' means aspects of the celestial of the spiritual. This is clear from the representation of 'Joseph' as the celestial of the spiritual, dealt with in 4286, 4592, 4963, 5307, 5331, 5332; consequently aspects of the celestial of the spiritual are meant by 'the house of Joseph'.
