Paradox #1
Deuteronomy 2:31 states that God gives the land of Sihon to the Israelites. A potential contradiction or conflict could be about the morality of God commanding the taking of land from others, which can seem inconsistent with teachings about loving one's neighbor and promoting peace. Some people might see a conflict between these commands and the broader message of love and justice in the Bible.
Paradox #2
The contradiction in this verse could be seen in the promise or command of taking over a land that already belongs to others. This can conflict with modern values of sovereignty and peaceful coexistence.
