History & Origin

Isaiah comes from the Hebrew Yeshayahu, meaning 'Yahweh saves' or 'God is salvation,' from yasha (to save, deliver) and Yah (a shortened form of Yahweh). Isaiah son of Amoz was one of the major Hebrew prophets, active in Jerusalem in the 8th century BC. His book is the longest of the prophetic books and is extensively quoted in the New Testament.

Isaiah was occasionally used in the English-speaking world from the 17th century onward but remained uncommon until the late 20th century. It entered the U.S. top 100 boys' names in the 1990s and the top 50 by the 2000s, where it has remained. Today it is one of the most fashionable Biblical boys' names, appealing for its strong meaning, musical sound, and distinguished prophetic heritage.

Did you know? The Book of Isaiah contains the famous messianic prophecy 'a virgin shall conceive' (Isaiah 7:14), one of the most quoted Old Testament passages in the New Testament, giving the name enormous theological significance.
