If you be affronted, it is better, in a foreign country, to pass it by in silence, and with a jest, though with some dishonour, than to endeavour revenge; for, in the first case, your credit's ne'er the worse when you return into England, or come into other company that have not heard of the quarrel.

Origin of endeavor
From American Heritage Dictionary of the English Language, 5th Edition
- The verb is from Middle English endeveren (“to make an effort”); the noun is from Middle English endevour, from the verb. Endeveren is from (putten) in dever (“(to put oneself) in duty”), from in + dever (“duty”), partially translating Middle French (se mettre) en devoir (de faire) (“(to make it) one's duty (to do), to endeavour (to do)”) (from Old French devoir, deveir (“duty”)).
