'Grass' in the Bible

And the first sounded, and there followed hail and fire, mingled with blood, and they were cast upon the earth: and the third part of the earth was burnt up, and the third part of the trees was burnt up, and all green grass was burnt up.

And it was said unto them that they should not hurt the grass of the earth, neither any green thing, neither any tree, but only such men as have not the seal of God on their foreheads.
