Answer:
My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from noah's ark won quick release.
Halo of water, tongue of wood. Skin of stone, long I've stood. My fingers short reach to the sky. Inside my heart men live and die.
I am nothing but holes tied to holes, yet am strong as iron.
Thousands lay up gold within this house. But no man made it. Spears past counting guard this house, but no man wards it.
As a whole, I am both safe and secure. Behead me, I become a place of meeting. Behead me again, I am the partner of ready. Restore me, I become the domain of beasts.
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
