The first part of the book assumes the background of conflicts among Israel, JudahJudah was the name of Jacob's fourth son and one of the 12 tribes., Syria, and Assyria. Chapters 7 and 8 especially reflect the Syro-Ephraimite war in which Syria and Israel (Ephraim) attacked Judah, perhaps in an attempt to remove King AhazJudean king in the time of Isaiah who engaged in pagan worship and placated the Assyrians. (735-715 BCE) and force Judah to join a coalition against the expanding kingdom of Assyria. Isaiah urged Ahaz to “stand firm in faith” (Isaiah 7:9), relying on God’s promises to protect the Davidic throne, rather than allying himself with Assyria, but Ahaz rejected this counsel (2 Kings 16:5-9). Assyria came to the aid of Judah, but success was short-lived. After Assyria had conquered Damascus (Syria) in 732, BCEit moved against Israel, destroying Samaria in 722/721 BCE (the fallThe Fall refers specifically to the disobedience of Adam and Eve when they listened to Satan rather than adhering to God's command not to eat the fruit from the tree. When people act contrary to God's will, they are said to fall from from grace... of the northern kingdomThe Northern Kingdom consisted of ten of the twelve tribes of Israel and lasted for 200 years until it was destroyed by Assyria in 721 B.C.E. In the northern kingdom the kings were evil. Prophets like Elijah and Amos railed against them and their evildoing.). Judah, the southern kingdomThe Southern Kingdom consisted of two tribes of Israel, Judah and Benjamin. Jerusalem was its capital, and the kingdom lasted from 931-586 B.C.E. As with the Northern Kingdom many of the kings were wicked, and prophets like Isaiah, Jeremiah, and Ezekiel spoke their often judgmental..., then became a vassal state of the Assyrian empire.
Later, Isaiah again urges reliance on God when HezekiahJudean king noted for his reforms in time of Isaiah. revolts against SennacheribSennacherib was the Assyrian king who besieged Jerusalem during the reign of Hezekiah., the Assyrian king (about 705-701 BCE), and seeks an alliance with Egypt (Isaiah 30:15b, 18; 31:1). Sennacherib is, in fact, defeated, and Jerusalem is spared (Isaiah 37:36-38). In all these events, Israel and Judah are buffeted between the great powers of the day, Egypt to the south and west, Assyria and Babylon to the north and east. The two kingdoms of God’s people seek advantage in one way or another, but the prophets, including Isaiah, recognize that the only advantage for such politically insignificant states is their reliance on the promises and protection of God. For the prophets, these promises include the coming messianic kingdom when God’s rule will be complete (see, for example, Isaiah 2:1-4; 9:2-7; 11:1-9).
Ahaz and Hezekiah are representatives of two different ways to relate to YHWH: distrust (Ahaz) and trust (Hezekiah). In the second part of the book, Babylon has become the great power, replacing Assyria, and has destroyed Jerusalem and taken many of its people captive (597 and 587 BCE). Now a new prophet, sometimes called “Second IsaiahSecond Isaiah refers chapters 40-55 of the book of Isaiah. This work was likely written during Israel's exile in Babylon (597-538 B.C.E.). Second Isaiah includes poetic passages of hope as well as descriptions of the Suffering Servant.,” preaches words of comfort, promising that God will bring release to the exiles (chapters 40-55). This happens around 538 BCE, when the Persian ruler, CyrusPersian leader who allowed Jewish exiles to return home., captures Babylon. The exiles’ return and the reestablishment of a new life in Jerusalem form the background of the final part of the Book of Isaiah (chapters 56-66).
