As far as I know, the word
"corpse" is used [besides OT 2Ki19:35 "dead
corpses, Isa37:36 "dead
corpses," Nah3:3 (2x;
of the "slain")]
in Mark 6:29, and is speaking of "dead BODY/BODIES"...
"corpse [G4430]" which word is also used
in Matthew 24:28 and
Revelation 11:8, 9(2x).
Contrastly, the word for
"dead [G2348]" can either mean "
physically dead" (a 'dead' body), or another kind of dead (tho same word), as here: "But she living in self-indulgence
is dead [G2348 - PERFECT indicative]
while living."
1Tim5:6 -

see the 9th occurrence, of 9x total)
[
note: the phrase
"the body of this death" Rom7:24 is
not referring to our physical bodies, as many suppose]
