Matthew 5:43
You have heard that it was said, You shall love your neighbor and hate your enemy. The sixth and final antithesis introduces a saying that is partially biblical (love your neighbor is from Leviticus 19:18) and partially traditional (hate your enemy appears nowhere in the Hebrew scriptures). The tradition had apparently reasoned from love your neighbor to the implied converse: if neighbor-love is commanded, then enemy-hatred is permitted or even required. Jesus denies this inference and challenges both the identification of neighbor with the in-group and the permission to hate anyone.
