Flavius Josephus, Against Apion
William Whiston, A.M., Ed.

[232] Now as for ourselves, I venture to say that no one can tell of so many; nay, not of more than one or two that have betrayed our laws, no, not out of fear of death itself; I do not mean such an easy death as happens in battles, but that which comes with bodily torments, and seems to be the severest kind of death of all others. Now I think those that have conquered us have put us to such deaths, not out of their hatred to us when they had subdued us, but rather out of their desire of seeing a surprising sight, which is this, whether there be such men in the world who believe that no evil is to them so great as to be compelled to do or to speak any thing contrary to their own laws. Nor ought men to wonder at us, if we are more courageous in dying for our laws than all other men are; for other men do not easily submit to the easier things in which we are instituted; I mean working with our hands, and eating but little, and being contented to eat and drink, not at random, or at every one's pleasure, or being under inviolable rules in lying with our wives, in magnificent furniture, and again in the observation of our times of rest; while those that can use their swords in war, and can put their enemies to flight when they attack them, cannot bear to submit to such laws about their way of living: whereas our being accustomed willingly to submit to laws in these instances, renders us fit to show our fortitude upon other occasions also.
