'Jehovah is salvation' (Yesha'yahu) — son of Amoz, prophesying in JERUSALEM across the reigns of four kings, roughly 740-700 BC. He is the one prophet the books show moving in and out of the palace: he confronts AHAZ at the conduit of the upper pool (7:3), advises HEZEKIAH through Sennacherib's siege (36-37), and rebukes him over the Babylonian envoys (39). He is married to a woman called 'the prophetess' and gives his sons sign-names — Shear-Yashub, 'a remnant will return,' and Maher-shalal-hash-baz. ⚠ Whether the whole of the book that bears his name comes from him is the most-argued question in Old Testament studies (see the book introduction). A later Jewish tradition, preserved in the Ascension of Isaiah and the Talmud (Yevamot 49b), has Manasseh saw him in two — which is probably what Hebrews 11:37 means by 'they were sawn asunder.'
