The narrative Source BII includes a meeting of three Assyrian commanders accompanied by a large army with a Judean delegation at the conduit of the upper pool on the highway at the Fuller’s Field. Rāb-šaqê conveys to Hezekiah’s emissaries a message. He warns them not to rebel against Assyria, not to confront the Assyrian army with the aid of the Egyptians in a pitched battle, and not to trust YHWH for deliverance, since YHWH has allegedly sent Sennacherib to devastate the land of Judah. When Hezekiah sends a delegation to Isaiah to ask for YHWH’s aid, Isaiah delivers an oracle assuring the king of Judah not to fear, for a spirit will be given to the king of Assyria. He will hear a rumor, retreat to Assyria, and die by the sword. Source BII focuses on the murder of Sennacherib, on the Egyptian aid in a pitched battle, and mentions Taharqa, king of Kush, who would cause Sennacherib to retreat. The motifs of divine intervention, causing Assyria’s defeat and Sennacherib’s retreat and eventual murder, are the backbone of Source BII.

In Chapter 5, it is shown that Source BI reflects the events and atmosphere during the days of the Assyrian campaign of Sennacherib in 701 BCE. The Assyrians devastated Judah in Sennacherib’s third campaign – a claim corroborated by 2 Kgs 18:14–16; Mic 1:10–16 and Isa 1:4–9, and the extensive archaeological excavations and surveys of the Judean kingdom. 2 Kings 18:14–16 (source A) preserves an account of Hezekiah’s subjugation to Sennacherib and payment of an enormous tribute. Hezekiah’s submission occurred, according to the biblical narrative, at the beginning of Sennacherib’s campaign against Judah. Following the payment, Sennacherib sent his envoys to demand Hezekiah’s capitulation. The Assyrian annals describe the total submission of Hezekiah and a victory over his Egyptian allies. Hezekiah remained king of Judah and was not punished. The original Source BI, portraying the events during the 701 campaign, did not contain a description of an Assyrian defeat nor of the murder of Sennacherib, which occurred twenty years after his campaign to the Levant.

In Chapter 12, I investigate the intertextual relations between Isa 36–37 and the rest of the book of Isaiah. First, Isa 36–39 uses terminology that is characteristic of the entire book of Isaiah. The question arises if these terms are characteristic of Isaiah son of Amoz, and later authors and redactors embraced them, or whether these terms stem from a later hand, and a later redactor inserted them into Proto-Isaiah. Secondly, the intertextual relations between Isa 36–39 and Proto-Isaiah are investigated. I focus primarily on the so-called Denkschrift (Isa 6:1–9:6, and esp. Isa 7), Isa 20, and Isa 31. Thirdly, the suggestion that Isa 36–39 was originally part of an independent scroll, which contained historical narratives about Isaiah (Isa 7; 20; 36–39), is evaluated. Lastly, the claim that Isa 36–39 is a literary bridge between Proto-Isaiah and Deutero-Isaiah is explored.

Isaiah 36–39 was not always a literary unit. Initially, the chapters deal with different historical events. The historical setting of Isa 38 and 39 is in the time of Sargon II (possibly 711 BCE). At some point in time, Isa 36–37 were joined to Isa 38 and 39, which were consequently moved to the end of the unit. This newly created block of stories about Hezekiah and Isaiah was inserted as a self-contained and coherent literary unit in the book of Isaiah (Isaiah 36–39) and the book of Kings (2 Kgs 18:13–20:19).

Previous scholars noticed the differences between the versions of Isa 38, 39 and 2 Kgs 20. Isaiah 38 diverges significantly from 2 Kgs 20:1–11. The differences between Isa 39 and 2 Kgs 20:12–19 are minor. The stages of redaction in these chapters are similar to the stages, which were identified in Isa 36–37. Source BI and Strand BIII, as well as the deuteronomistic redactor of Kings, can be detected. A late redactor added Hezekiah’s prayer in Isa 38:9–20. Verses 21–22 were possibly added to ch. 38 at a later stage by Trito-Isaiah.
