based on the kjv lexicon on Biblehub I have to agree with Dr. Mcfall and the other 4 discourses of the gospels seem to support it.
Matthew 19:9 ...
"οτι - hoti hot'-ee:" "causative, because" "-- as concerning that, as though, because (that), for (that), how (that), (in) that, though, why."
"ος - hos hos: nominative singular masculine" "who, which, what, that -- one, (an-, the) other, some, that, what, which, who(-m, -se), etc."
"αν - an an:" "denoting a supposition, wish, possibility or uncertainty"
"απολυση - apoluo ap-ol-oo'-o: third person singular" "to free fully, i.e. (literally) relieve, release, dismiss (reflexively, depart), or (figuratively) let die, pardon or (specially) divorce"
"την - ho ho: accusative singular feminine" " the, this, that, one, he, she, it, etc."
"γυναικα - gune goo-nay':" "a woman; specially, a wife -- wife, woman."
"αυτου - autos ow-tos': genitive singular masculine" "the reflexive pronoun self, used of the third person , and (with the proper personal pronoun) of the other persons"
"μη - me may:" "any but (that), forbear, God forbid, lack, lest, neither, never, no (wise in), none, nor, (can-)not, nothing, that not, un(-taken), without."
"επι - epi ep-ee':" "meaning superimposition (of time, place, order, etc.), as a relation of distribution (with the genitive case), i.e. over, upon, etc.; of rest (with the dative case) at, on, etc.; of direction (with the accusative case) towards, upon, etc."
"πορνεια - porneia por-ni'-ah: dative singular feminine" "harlotry (including adultery and incest); figuratively, idolatry -- fornication."
"και - kai kahee:" "and, also, even, so then, too, etc.; often used in connection (or composition) with other particles or small words"
"γαμηση - gameo gam-eh'-o: third person singular" "to wed (of either sex) -- marry (a wife)."
"αλλην - allos al'-los: accusative singular feminine" "else, i.e. different (in many applications) -- more, one (another), (an-, some an-)other(-s, -wise)."
"μοιχαται - moichao moy-khah'-o: third person singular" "to commit adultery -- commit adultery"
"και - kai kahee:" "and, also, even, so then, too, etc.; often used in connection (or composition) with other particles or small words"
"ο - ho ho: nominative singular masculine" "the, this, that, one, he, she, it, etc."
"απολελυμενην - apoluo ap-ol-oo'-o: singular feminine" "to free fully, i.e. (literally) relieve, release, dismiss (reflexively, depart), or (figuratively) let die, pardon or (specially) divorce"
"γαμησας - gameo gam-eh'-o: nominative singular masculine" "gameo gam-eh'-o: to wed (of either sex) -- marry (a wife)."
"μοιχαται - moichao moy-khah'-o: third person singular" "to commit adultery -- commit adultery."
"...because he wishes to divorce (let die figuratively) her, the wife; he shall not lay with another woman (recalling the other person of autos) to fornicate with her or marry another wife to commit adultery with her. For, [apoluo) he divorced her/(he) whom the divorced woman][(gameo) he is married/marries]; he commits adultery."
The other accounts in the gospel read likewise (matthew 5:32, luke 16:18, mark 10:11-12 john 8). Matthew 5 contains a lovely thought in the verse concerning that divorce teaches that God causes judgment and reckoning and john is ambiguous as to whether the woman the woman has a boyfriend who is married or has married a divorce man but warns her to separate from him because from that day, she is told, she "will miss the mark and lose her prize."
