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.

Footnotes:

'Vestments' signify truth, and in relation to the Lord, divine truth. 'Vesture' signifies truth that clothes good, and when describing the Word, it signifies the Word in its literal sense, like a garment that clothes its spiritual and celestial sense.

In 2 Kings 10:22, the vestments for the worshippers of Baal signify the falsities of idolatrous worship -- the opposite of truth. (Arcana Coelestia 1372)
