You have heard that it has been said, You shall love your neighbor, and hate your enemy.
There is a story told of Louis XII. of France. He had many enemies; and when he succeeded to the throne, he caused a list of these to be drawn up, and marked against each of their names a large black cross. When this became known, the enemies of the king fled, because they thought it was a sign that he intended to punish them. The king, hearing of their alarm, recalled them, and gave them an assurance of his good will, saying that he had placed a cross beside their names to remind him of the Cross that brings pardon to all; and he urged them, by his own example, and especially by the example of Him who prayed for His enemies, to go and do likewise.
