The Bronze Serpent on a Pole

Moses made a bronze serpent set it on a pole is this Hebrew term nace. This term can be rendered banner or standard or you could even translate it signal. In Isaiah 11, as he prophesies of this new Exodus that is going to be accomplished, I think the logic of this is this is part of the whole complex of events that have to do with the Exodus from Egypt and the conquest of the land.
