I was kind of surprised to find that one of the inscriptions on one of the towers at the Hoover Dam has what I thought was a typo, but I want to know if I'm in the wrong because I can't find anything online about this being a typo.
The tower says:
"Since primordial times, American Indian tribes and Nations lifted their hands to the Great Spirit from these ranges and plains. We now with them in peace buildeth again a Nation." (https://www.usbr.gov/lc/hooverdam/history/essays/artwork.html)
In the second sentence it seems that "buildeth" should read "build". Am I missing something? or is this a typo that has survived without comment for some 80 years on a very famous monument?
