'Green' in the Bible

Then you will know [without any doubt] that I am the Lord, when their slain are among their idols around their altars, on every high hill, on all the tops of the mountains, under every leafy tree and under every oak with thick branches, the places where they offered sweet incense and a soothing aroma to all their idols.

All the trees of the field will know that I the Lord bring down the tall tree, exalt the low tree, dry up the green tree, and make the dry tree flourish. I am the Lord; I have spoken, and I will fulfill it.”

and say to the forest of the Negev, ‘Hear the word of the Lord: thus says the Lord God, “Behold, I am about to kindle a fire in you, and it will devour every one of your green trees, as well as every one of your dry trees. The blazing flame will not be quenched and the whole surface from the south to the north will be burned by it.
