'Herb' in the Bible

For thus said Jehovah unto me, 'I rest, and I look on My settled place, As a clear heat on an herb. As a thick cloud of dew in the heat of harvest.

And their inhabitants are feeble-handed, They were broken down, and are dried up. They have been the herb of the field, And the greenness of the tender grass, Grass of the roofs, And blasted corn, before it hath risen up.
