'Good for nothing' in the Bible

everyone will be ashamedbecause of a people who can’t help.They are of no benefit, they are no help;they are good for nothing but shame and reproach.

And throw this good-for-nothing slave into the outer darkness. In that place there will be weeping and gnashing of teeth.’

In the same way, when you have done all that you were commanded, you should say, ‘We are good-for-nothing slaves; we’ve only done our duty.’”
