I learnt about 𝔊967 last week. This is a version of Ezekiel which did not make the Hexapla. Its (Greek) basis had meanwhile made its way into Latin - in the "Wirceburg" parchment copied in the fifth century but assuredly translated before Jerome, who rejected it. (That parchment was subsequently written over, which palimpsest got sent to Wirceburg.) The subset of Biblical scholars who care about Ezekiel (who aren't many) need to deal with it. Tracy McKenzie is dealing with it. It doesn't have Ez 36:23bβ–38.
Even before this (rare) 𝔊967 text was found in these two languages, scholars had noted its minus Ez 36:23bβ–38 as being... different, in our Greek. In 1903 Thackeray called it out as "Theodotionic" - which means late. Was anyone aware of this passage when the rest of Ezekiel was being translated? Johann Lust thought not.
Some scholars think Lust went too far. Absent the minus, which is "plus" in our canon, Ez 36:16–23bα remains as abnormally short for an oracle. Also the full Ez 36 is extant in Masada, along with other MT-like Biblical text.
McKenzie's main argument is a commentary upon MT / Theo Ez 36:23bβ–38. This uses the water-shedding of Numbers 19:13,20 (zrq; usually the Bible would have the shedding be of blood); along with other Ezekielian tropes. She backs up Lust inasmuch the passage be late. Then the question turns to what comes after v. 23bα, if not bβ+.
𝔊967 follows Ez 36:16–23bα immediately with 38:1. McKenzie notes this means the defilement of Israel may be cleansed only by Gog and Magog, whom Lord God YHWH is summoning upon the defilers. The dry-bones of our Ez 37 must await the end of our 38-39. Interestingly McKenzie doesn't like that, either. She follows "Tooman 2010" here, that Ez 38-39 is a floating oracle like so many PseudoEzekiels in Qumran. In that case Ez 37 is where it should be. The (in)famous Ez 40-48 block, by our count, would then follow Ez 37 directly, its own self.
The bibliography fails us for Tooman; I suspect McKenzie refers here to Gog of Magog. Not everybody approves the extremity of Tooman's late date, but even Tooman's harshest critic (pdf) agrees Ez 38-39 were/was fathered upon the prophet by someone else.
A more nagging problem is that we don't own any ur-text. We have 𝔊967 which smells like an apocalyptic rant; and we have our MT (and Jerome, and Peshitta et al.), which like McKenzie would dismiss the apocalypse... but they still have 38-39 too. Why not just refuse 'em? Jeremiah LXX merrily refused a lot of MT additions until the end. On the other-side to this day the Jews refuse the Greeks' Daniel (as they should), as well as Tobit (ditto).
