Matthew 19:4 And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, [kjv]
ο δε αποκριθεις ειπεν αυτοις ουκ ανεγνωτε οτι ο ποιησας κτισας απ αρχης αρσεν και θηλυ εποιησεν αυτους [gnt]
Some in the culture have trouble determining the difference between
"male" and
"female".
In the beginning, the gene pool was not contaminated. Mutations after that could, in certain cases, muddy the waters. Note that in order to
answer a question, Jesus (and others) must "
discern" (
not judge in a judicial sense) since that Greek word is the root word of the word for "
answer".
