What does the Bible say about enmity between Jews and Gentiles?

In Ephesians 2:14-16, it is explained that Jesus is our peace who has made both Jew and Gentile one by breaking down the dividing wall of hostility. This enmity was rooted in the law and cultural separation, which created a mutual hatred between Jews and Gentiles. However, through Christ's death and resurrection, this enmity was abolished, allowing for reconciliation into one body, as stated in Romans 12:5 and 1 Corinthians 12:12-13. The significance of this is profound, as it underscores the unity found in Christ, transcending former divisions of race, culture, and status.
