No thanks to a commentary.........the facts and characteristics are clear enough.....and the above is pure speculation....
Actually it makes the most sense - even if the 144k were married they would still not be "defiled with women", scripture no where claims that marriage is to be "defiled with women"
So John's figurative description of them as not idolatrous (virgins) which is described as fornication and harlotry in the bible.
Hosea 4:15 Though thou, Israel, play the harlot, yet let not Judah offend; and come not ye unto Gilgal, neither go ye up to Bethaven, nor swear, The LORD liveth.
2 Cor 11:2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
