'Unprofitable' in the Bible

and the unprofitable servant cast ye forth to the outer darkness; there shall be the weeping and the gnashing of the teeth.

So also ye, when ye may have done all the things directed you, say -- We are unprofitable servants, because that which we owed to do -- we have done.'

All did go out of the way, together they became unprofitable, there is none doing good, there is not even one.

and foolish questions, and genealogies, and contentions, and strivings about law, stand away from -- for they are unprofitable and vain.

who once was to thee unprofitable, and now is profitable to me and to thee,

Be obedient to those leading you, and be subject, for these do watch for your souls, as about to give account, that with joy they may do this, and not sighing, for this is unprofitable to you.
