In Matthew 5:43-44, Jesus says “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you,Love your enemies and pray for those who persecute you..” The part about loving your neighbor is cited in Leviticus 19:18, while it is said that the part about hating your enemies is what Jesus heard the Pharisees preach. Nowhere in the Old Testament does it say to hate your enemy.
Our enemies are those that uphold evil. So in that regard, between those who hate others because of their race or the way they worship the one true God, or where they are from, and those that are hated for such, who is REALLY the enemy to us?
