“A foe to God was never true friend to man”
“... a man's most useful friend and fearsome foe is the poet.”
“You shall judge of a man by his foes as well as by his friends.”
“Truth ever lovely - since the world began, The foe of tyrants, and the friend of man.”
“Never make excuses. Your friends don't need them and your foes won't believe them.”
“An injured friend is the bitterest of foes.”
