Isaiah 1 is the first chapter of the Book of Isaiah, one of the Book of the Prophets in the Hebrew Bible, which is the Old Testament of the Christian Bible. In this "vision of Isaiah concerning Judah and Jerusalem", the prophet calls the nation to repentance and predicts the destruction of the first temple in the siege of Jerusalem. This chapter provides an introduction to the issues of sin, judgement, and hoped-for restoration which form the overarching structure of the whole book. It concludes (verse 31) with 'a reference to the burning of those who trust in their own strength', in a fire which cannot be 'quenched' (Hebrew root: k-b-h), a relatively rare word which is also used in the last verse of the book (verse 66:24: 'their fire shall not be quenched'), thereby linking together beginning and ending of this whole book. It is traditionally read on the black sabbath immediately preceding the 9th of Av fast day. The original text was written in Hebrew language. This chapter is divided into 31 verses. Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text tradition, which includes the Codex Cairensis (895), the Petersburg Codex of the Prophets (916), Aleppo Codex (10th century), Codex Leningradensis (1008). Fragments containing parts of this chapter were found among the Dead Sea Scrolls (3rd century BC or later): 1QIsaa: complete 4QIsaa (4Q55): extant: verses 1‐3 4QIsab (4Q56): extant: verses 1‐6 4QIsaf (4Q60): extant: verses 10‐16, 18‐31 4QIsaj (4Q63): extant: verses 1‐6 There is also a translation into Koine Greek known as the Septuagint, made in the last few centuries BCE. Extant ancient manuscripts of the Septuagint version include Codex Vaticanus (B; B; 4th century), Codex Sinaiticus (S; BHK: S; 4th century), Codex Alexandrinus (A; A; 5th century) and Codex Marchalianus (Q; Q; 6th century). The parashah sections listed here are based on the Aleppo Codex. Isaiah 1 is a part of the Prophecies about Judah and Israel (Isaiah 1-12). {P}: open parashah; {S}: closed parashah.
