If you wou'd be reveng'd of your enemy, govern your self
Do good to your friends to keep them, to your enemies to win them.
You and I were long friends : you are now my enemy, and I am yours.
The nearest I can make it out, Love your Enemies means, Hate your Friends
Lend money to an enemy, and thou will gain him, to a friend and thou will lose him.
I have met the enemy, and it is the eyes of other people.
Hear not ill of a friend, nor speak any of an enemy.
Love your Enemies, for they tell you your Faults.
