Thus saith the Lord GOD; Because the Philistines have dealt by revenge, and have taken vengeance with a despiteful heart, to destroy it for the old hatred; / Therefore thus saith the Lord GOD; Behold, I will stretch out mine hand upon the Philistines, and I will cut off the Cherethims, and destroy the remnant of the sea coast.

Say to them that are of a fearful heart, Be strong, fear not: behold, your God will come with vengeance, even God with a recompence; he will come and save you.

For the taking of revenge, a man locks himself up alone and thinks. His stomach must be empty for his head to be full. Vengeance comes a little from the heart and a lot from the mind; one must take oneself apart from the noise of men and of things, even from what resembles them; only the voices of bells and of thunder are allowed. Let the room in which you meditate be dark, narrow and warm.

Revenge tightens the heart as much as the jaw. (La vengeance serre le cœur - Autant que la mâchoire)

... Life can be savored only if you look to the future and leave vengeance to the gods
