The massive Assyrian invasion of Judah in 701 (reflected in 2 Kgs 18,13b; 18,1719,37) has apparently been confused with an earlier, limited invasion in Hezekiahs 14th year (reflected in 2 Kgs 18,13a.14-16; 2 Kgs 20; 2 Chr 32; Isa 22). Historically, this earlier campaign can best be dated to 712, when Sargon II apparently led the Assyrian royal guard on a Palestinian campaign. Chronologically, this dating fits perfectly with e.g. recent dating of the definitive fall of Samaria (2 Kgs 18,9: in Hezekiahs 6th year) to 720. 2 Kgs 18,9s parallel dating to Hosheas 9th year agrees with his apparent accession in 731 or 729. Dating Menahems death to 743 (as required, following biblical data, to avoid a triple overlap among Uzziah, Jotham and Ahaz) agrees with Eponym Chronicle evidence for this dating of 2 Kgs 15,19-20s presumably already desperate fiasco, and is consistent with a plausibly composite 738 tribute-list naming Menahem. Combining these datings produces a workable later 8th century biblical chronology.
Further support for linking Isa 22,15-24 to the pre-2 Kgs 18,1719,37 / pre-701 campaign worked out thus far is provided by several points of contact between these verses and 2 Kgs 2021. Cf.: (1) the exceptionally harsh, personal prophecy against the chief minister in Isa 22,15-19 with the equally harsh prophecy against the royal family in 2 Kgs 20,17-18; (2) the surprising prominence of the chief minister rather than the king in Isa 22,15-19 (dated c. vv. 1-14s invasion) with the invasion / near-fatal royal illness in 2 Kgs 20,1-11; (3) the remarkably exalted position promised to Eliakim, including power over "the key of the house of David" (Isa 22,22), with the compounding of Hezekiahs illness by his lack of sons (2 Kgs 20,18)22.
Additional material in 2 Chr 32 likewise supports confusion of the campaign reflected in 2 Kgs 18,13b; 18,1719,37 with an earlier (i.e. pre-701) and much less destructive Assyrian campaign against Hezekiah: vv. 22-23 state that Hezekiah was "held in high honour by all the nations" and received many (diplomatic) gifts in the wake of vv. 9-21s invasion (which transparently reprises that of 2 Kgs 18,1719,37), and vv. 24-25 state that Hezekiahs heart was "proud" following a serious illness23.
