'Green' in the Bible

So He directed them to make all sit down in companies on the green grass.

For if they are doing these things in the case of the green tree, what will be done in that of the dry?"

The first blew his trumpet; and there came hail and fire, mixed with blood, falling upon the earth; and a third part of the earth was burnt up, and a third part of the trees and all the green grass.

And they were forbidden to injure the herbage of the earth, or any green thing, or any tree. They were only to injure human beings--those who have not the seal of God on their foreheads.
