ORIGIN & HISTORY

About the name

Yahweh is salvation — inherited directly from the Hebrew name Yəšaʿyāhū (Isaiah), of which Isaias is a Latin Vulgate variant form.

יְשַׁעְיָהוּ (Yəšaʿyāhū, Biblical Hebrew). The prophet Isaiah, after whom the name (and its Latin form Isaias) is named, was an 8th-century BCE Israelite prophet whose ministry, according to biblical tradition, spanned roughly 64 years across the reigns of four Judahite kings (Uzziah, Jotham, Ahaz, and Hezekiah), beginning around 740 BCE.
Mythological and religious contextIn Judaism, Isaiah is venerated as a major prophet, with rabbinic literature expanding on his biography and his feast day observed on May 9 in some traditions. In Christianity, the Book of Isaiah is central to New Testament exegesis, with the "Songs of the Suffering Servant" widely read as prophetic of Jesus Christ; the Church Father Jerome called him "more of an Evangelist than a Prophet." In Islam, though not named directly in the Quran, Isaiah is recognized in Islamic scholarly tradition as a prophet who foretold the coming of both Jesus and Muhammad.
