The Bible does not provide a specific age at which the prophet Isaiah died. However, historical sources and traditions suggest that he may have lived into his 60s or even 80s. The Book of Isaiah does not mention his age, and details about his death are scarce. Some Jewish traditions imply that he was martyred during the reign of King Manasseh, which was around 700-600 B.C. This speculation helps give context to his life and the challenges he faced as a prophet during a tumultuous time in Israel’s history.
While we can’t pinpoint his exact age, the uncertainty makes Isaiah’s prophetic messages even more significant, as they addressed critical issues of faith, morality, and the future of God’s people.
