Contradiction with Genesis 19:30-36
These verses narrate the story of Lot's daughters who, fearing the end of their family line, commit incest with their father, an act condemned in Deuteronomy 27:23 as cursed.
Genesis 19:30-36: And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar: and he dwelt in a cave, he and his two daughters.
Contradiction with 2 Samuel 13:11-14
This passage describes Amnon's rape of his sister Tamar, an act of sexual immorality and disgrace that conflicts with the curse pronounced in Deuteronomy 27:23.
2 Samuel 13:11-14: And when she had brought [them] unto him to eat, he took hold of her, and said unto her, Come lie with me, my sister.
Contradiction with Leviticus 18:6-18
These verses provide laws against various forms of incest, which implies prohibition but does not directly pronounce a curse like in Deuteronomy 27:23.
Leviticus 18:6-18: None of you shall approach to any that is near of kin to him, to uncover [their] nakedness: I [am] the LORD. [near...: Heb. remainder of his flesh]
Paradox #1
The contradiction or conflict in that verse could be that it condemns a specific action while elsewhere in the Bible, similar actions or related circumstances might not be equally condemned or might even be described without direct moral judgment. This inconsistency can lead to confusion about the moral standards being promoted.
