'Good for nothing' in the Bible

And I went to the Euphrates, and digged, and took the girdle from the place where I had hid it; and behold, the girdle was spoiled, it was good for nothing.

This evil people, who refuse to hear my words, who walk in the stubbornness of their heart, and go after other gods, to serve them and to worship them, shall even be as this girdle which is good for nothing.
