4.The ESV translators situated in the year 2001 supply one plausible paraphrase for "false
flesh", arguably influenced by more recent Christian views, in making the phrase refer to
alleged illicit sexual activity of the Genesis account (cf. the language of the epistle
to the Romans 1:21-32 not specifically referring to Sodom).
Another theory is that it is just a reference to the “strange flesh” of the intended rape
victims, who were angels, not men. There is a counter-argument that focus on the fact
that the men of Sodom did not know that the strangers were angels.
A third opinion is based upon the fact that the same term of "false flesh" is used in the
Mosaic laws were within the context it is clearly referring to cannibalism as was common
in the people of Canaan that the Sodomites were part of.
The Jewish historian Josephus used the term “Sodomites” summarizing the Genesis narrative:
“About this time the Sodomites grew proud, on account of their riches and great wealth;
they became unjust towards men, and impious towards God, in so much that they did not
call to mind the advantages they received from him: they hated strangers, and abused themselves with Sodomitical practices” (Antiquities 1.11.1 [3] — circa A.D. 96). The final element of his assessment goes beyond the Biblical data, even in the New Testament.
