And I beheld a rod of iron, and it extended along the bank of the river, and led to the tree by which I stood.

And it came to pass that I beheld others pressing forward, and they came forth and caught hold of the end of the
rod of iron; and they did press forward through the mist of darkness, clinging to the rod of iron, even until they
did come forth and partake of the fruit of the tree.
