Tyre’s “70 Years” in Isaiah 23,15-18 417 SUMMARY Isaiah 23,15-18 has often been regarded as part of a Josianic redaction, aligning the temporal parameters of Isaiah’s oracle against Tyre with Josiah’s reign. Previous investigations into this passage, however, have relied on matters of strict chronology to establish this Josianic connection. The Josianic character of the passage is more readily evident through its invocation of an important cuneiform document from the reign of Esarhaddon, corresponding with other Josianic- era literary works strongly influenced by Assyrian rhetoric. Tyre’s “70 Years” deploys language once reserved for the Mesopotamian deity Marduk, contributing to the way in which a Judean audience in the 7th century should conceive of their own deity YHWH.
