The color green is almost exclusively used in connection with plants in the Bible, and the meaning is closely connected to the meaning of plants as well. Plants, in general, represent facts, knowledge that we can gather from the world. Green plants are ones that are alive and growing. Since life represents love and goodness, it makes sense that green plants are facts that have the potential for good use. It also indicates that they are the kinds of things we learn through directly through our senses, since to identify green plants we need to actually see the greenness.

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.
