Yeshua was Jesus’s name in the earliest translations of the Bible, with the longer version, Yehoshua, appearing a few hundred times in the Old Testament.
The New Testament was written in Greek, not in Hebrew or Aramaic, and Greeks did not use the “sh” sound, so evangelists substituted an “s” sound instead. Another “s” sound was added to the end of the name to create a more masculine name. So Yeshua became Iesous, which eventually became Jesus.
