'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.

For where a last will and testament is, there must of necessity be the death of him who made it.
