'Unprofitable' in the Bible

Throw out the unprofitable servant into the outer darkness, where there will be weeping and gnashing of teeth.'

They have all turned aside. They have together become unprofitable. There is no one who does good, no, not, so much as one."

but shun foolish questionings, genealogies, strife, and disputes about the law; for they are unprofitable and vain.

Obey your leaders and submit to them, for they watch on behalf of your souls, as those who will give account, that they may do this with joy, and not with groaning, for that would be unprofitable for you.
