Did Jesus "Je[hovah]-salvation" know God's name?

Michael Servetus participated in the Protestant Reformation and translated the Hebrew Bible into Latin. In July 1531, he published his De Trinitatis Erroribus (On the Errors of the Trinity) in which he explained clearly that the Trinity was a 3-headed monster. Accordingly, Catholics and Protestants alike condemned him. He was then arrested in Geneva and burnt at the stake as a heretic by order of the city's Protestant governing council. This book was translated into English only in 1932, but still worse, the main arguments from part V were completely distorted. For example he explained that God's name was Iehouah because in Hebrew this name was close to the name of Iesuah (Jesus), or Iehosuah, which means "Iehouah is salvation." He also knew that according to Paulus de Heredia, a Christian Cabbalist, the meaning of God's name was "He causes to be" (yehauueh), but he never confused the pronunciation of God's name with its Kabbalistic meaning (yehaweh). For Servetus, Iehouah was the only true God.
