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.
on the Shephelah is very consistent geographically with 2 Kgs 18,14-16 and politically with Hezekiahs prosperity, lack of repentance and ongoing plotting, apparently following 2 Kgs 20s campaign (above with nn.12-13). Likewise, the exceptionally harsh prophecy against stubbornly unrepentant high officials in Isa 22,14 is very plausibly connected politically to Hezekiahs extremely complacent reaction in 2 Kgs 20,19 (n. 13 above) to an equally harsh prophecy against the royal family.
Moreover, Isa 22,1-14 is widely and very plausibly dated to around the time of (presumably: slightly before) Isa 22,15-23(24), based on the extremely harsh and personal denunciations of unrepentant Judaean officials in both sections, the threat of exile to Mesopotamia (very widely accepted referent of "great wide land") in v. 18, and the repetition in vv. 15-16 of expressions used in vv. 1.1418.
As often accepted, dating Isa 22,15-23(24) to the time of the events reflected in 2 Kgs 18,1719,37 (or later) appears impossible because Eliakim is named in 2 Kgs 18,18.37 as the one who is "over the house" (cf. e.g. 2 Kgs 15,5: i.e. chief minister), but is only promised this post in Isa 22,20-21, when Shebna was "over the house" (v. 15)19. This dating also appears highly unlikely because Shebna repents in 2 Kgs 18,3719,2 but decidedly not in Isa 22,15-19. On the other hand, dating Isa 22,15-24 significantly earlier than the Judaean military disaster in 2 Kgs 18,1719,37 / 701 would allow dating the seeming addition in v. 25 early enough to accommodate its extremely natural explanation as criticism of Eliakims leading role in the 701 rebellion, couched in terms of the disaster that Isaiah expected as a result of this policy20.
