Paradox #1
Isaiah 9:21 might seem to show a contradiction or conflict in how people from the same nation harm each other despite being supposed to live together peacefully as part of God's chosen people. Instead of unity and compassion, there is division and violence, which goes against the moral teachings of love and harmony often emphasized in the Bible.
