'Herbage' in the Bible

“Behold, as wild donkeys in the desert,The poor go to their work, diligently seeking food;As bread for their children in the desert.

“I will lay waste the mountains and hillsAnd wither all their vegetation;I will turn the rivers into coastlandsAnd dry up the ponds.

“Shepherds with their flocks will come against her;They will pitch their tents all around her;They will pasture, each one in his place [eating up all her rich grasses].

“The doe in the field has given birth only to abandon her youngBecause there is no grass.

They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but [to hurt] only the people who do not have the seal (mark of ownership, protection) of God on their foreheads.
