In the Roman Martyrology we read that today the Church liturgically recalls Saint Isaiah, a major prophet in the Old Testament. A translation of the entry found in the Martyrology:
Commemoration of holy Isaiah, the prophet, who, in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, was sent to reveal that the Lord was faithful and a savior to an unfaithful and sinful people, and to fulfill the promise swear by God to David. It is said that he met death as a martyr at the hands of the Jews under king Manassah.
