Taking Advantage / Who & What Devours?

Luke 20:47    KJV
Which devour widows' houses, and for a
shew make long prayers: the same shall
receive greater damnation.

There are 13 Greek words from Strong's Lexicon:
G3739 - hos = who, which, what, that, whom, whose, whosoever
G2719 - katesthio = consume by eating, devour, squander, waste
G5503 - chera = widow
G3614 - oikia = inhabited house, dwelling, household, at home
G2532 - kai = and, also, even, both, then, likewise, indeed, but
G4392 - prophasis = pretence, cloke, (for) show, pretext, pretend
G4336 - proseuchomai = to offer prayers, to pray, pray for
G3117 - makros = long lasting; remote, distant, far off; lengthy
G4336 - proseuchomai = to offer prayers, to pray, pray for
G3778 - houtos = this one, he, they; (specifically) present visibly
G2983 - lambano = to take, lay hold of, take/carry away, to seize

something further, exceedingly abundant, greater, more
G2917 - krima = decree, judgment(s), condemnation (of wrongs),
punishment, sentence as judicial matter decided in court case

Marin's transliteration:
Whosoever squanders widows' inhabited dwellings likewise
pretending to offer long-lasting lengthy prayers [shall] this
one be taken to receive exceedingly greater condemnation.

The verse implies that this consumption is not a quick and
fast event, but a long, slow and methodical process to squander
the scarce resources of widows.

Strong's G2719 - Katesthio (verb) = to consume by eating,
to eat up, devour; i.e., to squander, waste (substance);
forcibly appropriate, to strip one of his goods (to ruin) by
the infliction of injuries; of the consumption of the strength
of body and mind

This form of devouring is specifically pointed directly against those
spiritual leaders who take advantage of their congregation who are
the least, the weakest, and the loneliest, namely elderly widows.

The LORD compared these false-prayers to the fowls of the air
as they both devour the good seed that's fallen into the ground,
or group of believers. Out of 10 verses, there was:
(a) one son who was devouring his father's resources through harlots
(b) One being consumed due to His zeal for His Heavenly Father
(c) believers allowing themselves to be taken advantage of by a man
(d) believers biting and devouring each other one by one

Fowls
Matthew 13:4 - fowls came and devoured
Mark 4:4 - fowls of the air came and devoured
Luke 8:5 - fowls of the air devoured

False-Prayers
Matthew 23:14 - woe to those who devour
Mark 12:40 - which devour widows' houses
Luke 20:47 - which devour widows' houses

Son Devouring Father's Resources
Luke 15:30 - son devoured by living with harlots

Son Consumed For Zeal Of His Heavenly Father
John 2:17 - zeal has eaten me up

Believers Getting Devoured
2 Corinthians 11:20 - if a man devour [you]

Believers Devouring Each Other
Galations 5:15 - if you bite and devour one another

Who and What are These Fowls?
Strong's G4071 - Peteinon (neuter noun) = flying, winged animals,
birds, fowl (of the heaven, of the air).

It's a bit of a guess, but I would view such devouring fowls as
a part of the kingdom of darkness that seek to draw all of Mankind
into waste places where needs are taken advantage of by those in
powerful places.
