Isaiah son of Amoz prophesied in Jerusalem under four kings of Judah: Uzziah, Jotham, Ahaz, and Hezekiah. In the year that King Uzziah died (c. 740 BC), he saw the Lord in the Temple, high and lifted up, his train filling the sanctuary, the seraphim crying 'Holy, holy, holy' — and one took a burning coal from the altar and touched his lips (Is 6).
He prophesied the virgin who would conceive and bear a son named Emmanuel (Is 7:14); the Prince of Peace upon whose shoulder the government would rest (Is 9:6); the shoot from the stump of Jesse (Is 11:1); and above all, the four Servant Songs — climaxing in Isaiah 52–53, the Suffering Servant who 'was wounded for our iniquities... and by his bruises we are healed.' No prophet is quoted more in the New Testament; the Fathers called him 'the Evangelist of the Old Testament.'
Jewish tradition (Martyrdom of Isaiah, c. 1st century BC) records that under the apostate King Manasseh, Isaiah was sawn in two inside a hollow tree — a death alluded to in Hebrews 11:37. He had prophesied for sixty years.
