THEY kill me, they cut my flesh: they persecute my person with curses. What then? May not thy mind for all this continue pure, prudent, temperate, just? As a fountain of sweet and clear water, though she be cursed by some stander by, yet do her springs nevertheless still run as sweet and clear as before ; yea though either dirt or dung be thrown in, yet is it no sooner thrown, than dispersed, and she cleared. She cannot be dyed or, infected by it. What then must I do, that I may have within myself an overflowing fountain, and not a well? Beget thyself by continual pains and endeavours to true liberty with charity, and true simplicity and modesty.
