I thought this was so interesting. I typed it out because of possible copyright infringement posting something not my own.....but Google the monument and see for yourself. Jehovah's name was very well known here in the US by the people who came from Europe searching for religious freedom.
The name Jehovah appears in the Church of S. Agata Santhia in Italy (Vercelli). It was once a household word. It was removed from the original manuscripts by Trinitarians who deleted it and replaced it with Lord and God. Now people don't know who God is.
