'Potsherds' in the Bible

Woe [to the] one who strives with his {maker}, a potsherd among potsherds of earth! Does [the] clay say to the one who fashions it, 'What are you making?' and 'Your work has no hands'?

And you will drink it, and you will drain [it], and its potsherds you will gnaw, and you will tear out your breasts, for {I myself} spoke," {declares} the Lord Yahweh.
