Contradiction with Matthew 5:28
This verse contradicts Deuteronomy 5:18, which states "Neither shalt thou commit adultery," by expanding the definition of adultery beyond physical acts to include lustful thoughts, implying that adultery includes intentions of the heart.
Matthew 5:28: But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
Paradox #1
The contradiction or conflict could be that the commandment conflicts with other narratives in the Bible where polygamy or having multiple partners was accepted or practiced by figures like King David or Solomon. This could create inconsistency between the commandment and the actions of biblical characters.
