'Dried up' in the Bible

For if people are doing these things [to me] while the [leaves of the] tree are green [i.e., to someone innocent of wrongdoing], what will they do when [the leaves] are dried up [i.e., to the sinful Jews of Jerusalem]?"

If a person does not remain united to me, he will be thrown out as a [fruitless] branch and dried up. People gather up such branches and throw them into the fire to be burned [as fuel ?].

And the sixth [angel] poured out his bowl on the great Euphrates River and its water was dried up, so that the road would be prepared for the kings from the east [to travel on].
