'Necessity' in the Bible
But he who stands steadfast in his heart, having no necessity, but has power over his own heart, to keep his own virgin, does well.
For if I preach the Good News, I have nothing to boast about; for necessity is laid on me; but woe is to me, if I don't preach the Good News.
But I was willing to do nothing without your consent, that your goodness would not be as of necessity, but of free will.
For the priesthood being changed, there is of necessity a change made also in the law.
