'Profiteth' in the Bible

It is the spirit that giveth life; the flesh profiteth nothing: the words that I have spoken unto you are spirit, are are life.

For circumcision indeed profiteth, if thou be a doer of the law: but if thou be a transgressor of the law, thy circumcision is become uncircumcision.

And if I bestow all my goods to feed the poor , and if I give my body to be burned, but have not love, it profiteth me nothing.
