'Rot' in the Bible

To one who shapes a pedestal,choosing wood that does not rot?He looks for a skilled craftsmanto set up an idol that will not fall over.

Why was no one there when I came?Why was there no one to answer when I called?Is My hand too short to redeem?Or do I have no power to deliver?Look, I dry up the sea by My rebuke;I turn the rivers into a wilderness;their fish rot because of lack of waterand die of thirst.
