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.
mobilization involved: "In a sudden rage, I did not (wait to) assemble the full might of my army or to prepare the camp(ing equipment), but started out towards Ashdod (only) with those of my warriors who, even in friendly areas, never leave my side".
Many chronological considerations and historical parallels support dating the Assyrian campaign in year 14 of Hezekiah to 71234. Chronologically, this dating agrees perfectly with chronographic reckoning back from the death of Josiah in 60935.
