Yahshua is a proposed transliteration of יהושוע, the original Hebrew name of Jesus. The pronunciation Yahshua is philologically impossible in the original Hebrew and has support neither in archeological findings, such as the Dead Sea scrolls or inscriptions, nor in rabbinical texts as a form of Joshua. Scholarship generally considers the original form of Jesus to be Yeshua, a Hebrew Bible form of Joshua.[1]
Usage and/or support of the name Yahshua is largely restricted to religious groups that are a part of (or otherwise associated with) the Sacred Name and Hebrew Roots which, among other things, advocate for the preservation of Hebrew / Arabic sacred names in translations of the Bible.
