'Means' in the Bible

or because of us by all means doth He say it? yes, because of us it was written, because in hope ought the plower to plow, and he who is treading ought of his hope to partake in hope.

I became to the infirm as infirm, that the infirm I might gain; to all men I have become all things, that by all means I may save some.

but I chastise my body, and bring it into servitude, lest by any means, having preached to others -- I myself may become disapproved.
