Text of Isaiah 42:20

“‘You have seen many things, but you pay no attention. Your ears are open, but you do not listen.’ ”


Immediate Literary Setting

Isaiah 42 begins with the presentation of Yahweh’s Servant who will bring justice to the nations (vv. 1-9), erupts in a new song of praise (vv. 10-17), then pivots in vv. 18-25 to expose Israel—the “servant” that should have been a light—as blind and deaf. Verse 20 stands at the heart of that indictment. The historical soil that produced this rebuke is Judah’s repeated refusal to heed the prophetic word during the era of Assyrian pressure and the looming Babylonian exile.


Isaiah’s Ministry and Dating

• Active ca. 740–681 BC (Isaiah 1:1; cp. 2 Kings 15-20).

• Served under Uzziah, Jotham, Ahaz, and Hezekiah—spanning roughly 60 years, a chronology that harmonizes with the Ussher timeline (creation 4004 BC; Isaiah’s prophecy c. 3270 AM).

• Isaiah received his commission “in the year that King Uzziah died” (Isaiah 6:1), about 740 BC, just as Assyria was re-emerging as a superpower under Tiglath-pileser III.


Political Backdrop: The Assyrian Threat

Assyria’s westward expansion dominated the region:

• Tiglath-pileser III (745–727 BC) exacted tribute from Ahaz (2 Kings 16:7-9).

• Shalmaneser V and Sargon II captured Samaria (722 BC), deporting Israel’s northern kingdom. Black basalt fragments from the Palace of Sargon at Khorsabad refer to the “people of Israel” being carried off—archaeological corroboration of 2 Kings 17.

• Sennacherib’s 701 BC campaign besieged Jerusalem. The Taylor Prism (British Museum BM 91032) boasts that he “shut up Hezekiah…like a caged bird,” and the 533-meter Hezekiah’s Tunnel—inscribed with the Siloam inscription (ca. 701 BC, now in the Israel Museum)—illustrates Judah’s frantic defensive measures.

Isaiah repeatedly warned Judah not to rely on diplomatic alliances (Isaiah 30:1-5) but to trust Yahweh—warnings largely unheeded, hence “ears are open, but you do not listen.”


Religious Climate: Syncretism and Idolatry

Despite witnessing Yahweh’s deliverance from Sennacherib (Isaiah 37:36-38), the populace continued sacrificing at high places (2 Kings 17:11). Isaiah attacked carved idols (Isaiah 40:18-20; 44:9-20), and chapter 42 contrasts the lifeless idols of the nations with the living, seeing-yet-ignored God. The stubbornness of Judah’s religious elite and laity alike forged the context for the “blind and deaf servant.”


Socio-Economic Pressures

Assyrian tribute drained Judah’s treasury (2 Kings 18:14-16). Agricultural lands were ravaged (Isaiah 5:8; 7:23-25). Archaeologists have uncovered LMLK (“belonging to the king”) storage jar handles around Hebron and Socoh, dated to Hezekiah’s reign—evidence of state-controlled grain reserves stockpiled for siege. Economic uncertainty amplified national anxiety, but instead of provoking repentance it fostered pragmatic, idol-tinged survivalism.


Prophetic Horizon: Babylon in View

Isaiah looked beyond Assyria to Babylon’s rise (Isaiah 39:5-7; chs. 40-48). The prediction of Cyrus by name (Isaiah 44:28; 45:1) anticipates a sixth-century deliverance; the Cyrus Cylinder (British Museum BM 90920) echoes Isaiah’s description of Cyrus as the liberator of exiles. Thus, Isaiah 42:20 exposes the blindness of a people who would soon see Jerusalem fall because they refused earlier warnings.


Theological Focus: Covenant Discipline

Isaiah 42:20 encapsulates Deuteronomy’s covenant curses (Deuteronomy 28:15-68). Yahweh’s servant-nation had the Law, prophets, and historical deliverances—“You have seen many things.” Yet covenant deafness demanded corrective exile (Isaiah 42:24-25). The motif of blindness prepares for the Servant-Messiah who will open blind eyes (Isaiah 42:6-7), fulfilled when Christ gave literal and spiritual sight (Luke 4:18-21; John 9).


Practical Implications

Historical context sharpens Isaiah 42:20’s warning: privileged exposure to revealed truth heightens accountability. Modern readers, standing amid manuscript reliability, archaeological corroboration, and the resurrected Christ’s attested reality (1 Corinthians 15:3-8), face the same choice—heed the evidence or remain willfully blind.


Summary

Isaiah 42:20 grew out of Judah’s 8th- to 7th-century BC milieu of Assyrian domination, entrenched idolatry, socio-economic strain, and looming Babylonian exile. Archaeology, epigraphy, and preserved manuscripts all converge to verify the setting, amplifying Scripture’s call to open ears and responsive hearts.
