פירוש על בבא קמא 4:20

As one who consumes with the tooth. Why is tooth referred to as golol? Rabbeinu Chananel explains that the word golol is related to tooth as we see in Ezra 6, “rows of marble stone.” We see that golol is used to describe marble. For a tooth is similar to marble stone. We therefore translate “as the golol consumes”- as the tooth consumes. The word y’vaer is used to describe the activity of the tooth, so too, the verse in the Torah u’vee’air refers to the activity of the tooth.
