Hi UntoBabes,
For further clarification of 'strange flesh', I looked up Berry's Greek Interlinear, which chooses 'other' instead of 'strange'.
Strong's Numbers offer these two: flesh
4561 sarx {sarx}
probably from the base of 4563; TDNT - 7:98,1000; n f
AV - flesh 147, carnal 2, carnally minded + 5427 1, fleshly 1; 151
1) flesh (the soft substance of the living body, which covers
the bones and is permeated with blood) of both man and beasts
2) the body
2a) the body of a man
2b) used of natural or physical origin, generation or
relationship
2b1) born of natural generation
2c) the sensuous nature of man, "the animal nature"
2c1) without any suggestion of depravity
2c2) the animal nature with cravings which incite to sin
2c3) the physical nature of man as subject to suffering
3) a living creature (because possessed of a body of flesh)
whether man or beast
4) the flesh, denotes mere human nature, the earthly nature of man apart
from divine influence, and therefore prone to sin and opposed to God
and 'other':
2087 heteros {het'-er-os}
of uncertain affinity; TDNT - 2:702,265; adj
AV - another 43, other 42, other thing 3, some 2, next day 2, misc 7; 99
1) the other, another, other
1a) to number
1a1) to number as opposed to some former person or thing
1a2) the other of two
1b) to quality
1b1) another: i.e. one not of the same nature, form, class,
kind, different
This, in the context of Sodom and Gomorrah, ties in with the descriptions of abominations in Lev 18:22, 23, which are also manifestations of 'fornication' as it is translated in the New Testament. There is no hint of aliens in the Greek.
Regarding the angels which left their first estate and habitation, might not these be they who followed Lucifer, and were drawn out of heaven with him by his tail?
