'Waistcloth' in the Bible

So I bought the waistband according to the word of the Lord and put it on my loins.

Then I went to the Euphrates and dug, and I took the waistband from the place where I had hidden it. And behold, the waistband was decayed and ruined; it was completely worthless.

These wicked and malevolent people, who refuse to listen to My words, who walk in the stubborn way of their heart and have followed other gods [which are nothing—just man-made carvings] to serve them and to worship them, let them be just like this waistband which is completely worthless.
