{When they shall rise from the dead} (hotan ek nekr(936e)
anast(9373)in). Second aorist active subjunctive with hotan
(hote plus an).  Mt 22:30  has it "in the resurrection,"  Lu
20:35  "to attain to the resurrection." The Pharisees regarded
the future resurrection body as performing marriage functions, as
Mohammedans do today. The Pharisees were in error on this point.
The Sadducees made this one of their objections to belief in the
resurrection body, revealing thus their own ignorance of the true
resurrection body and the future life where marriage functions do
not exist. {As angels in heaven} (h(9373) aggeloi en t(9369) ouran(9369)).
So  Mt 22:30 .  Lu 20:36  has "equal unto the angels"
(isaggeloi). "Their equality with angels consists in their
deliverance from mortality and its consequences" (Swete). The
angels are directly created, not procreated.
