'Worthless' in the Bible

So every good tree produces good fruits, but the worthless tree produces bad fruits.

A good tree cannot produce bad fruits, nor a worthless tree produce good fruits.

I tell you that on the day of judgment, people will give an account for every worthless word they speak.

and when it was full, they dragged it ashore, sat down, and gathered the good fish into containers, but threw out the worthless ones.

Throw out the worthless slave into the outer darkness; in that place there will be weeping and gnashing of teeth.
