Contradiction with Matthew 12:1-2
In Nehemiah 13:20, merchants were restricted from selling on the Sabbath, whereas in Matthew 12:1-2, Jesus' disciples plucked and ate corn on the Sabbath, suggesting a less strict interpretation of Sabbath observance.
Matthew 12:1-2: At that time Jesus went on the sabbath day through the corn; and his disciples were an hungred, and began to pluck the ears of corn, and to eat.
Paradox #1
The contradiction or conflict that could arise is the exclusivity and harsh treatment of outsiders or foreigners. This might clash with broader themes of love, compassion, and inclusion found elsewhere in religious teachings. This can create tension between maintaining a specific cultural or religious identity and the call to love all people.
