'Good for nothing' in the Bible

Then I went to the Euphrates, and dug, and took the sash from the place where I had hid it. And, behold, the sash was rotten. It was good for nothing.

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