The zeal of friends it is that knocks me down, and not the hate of enemies

The zeal of friends it is that razes me, And not the hate of enemies. [Ger., Der Freunde Eifer ist's, der mich Zu Grunde richtet, nicht der Hass der Feinde.]

A merely fallen enemy may rise again, but the reconciled one is truly vanquished.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

There are few things worse than mistaking an enemy for a friend.

God save me from my friends - I can protect myself from my enemies.
