Nachschlagewerk zu Ijow 28:17

Elisha also asked Rabbi Meir’s explanation of the verse, “She may not be valued in gold or in glass and vessels of pure gold are not her equal.” (Job, 28:17.) Rabbi Meir declared that the verse refers to the Torah which can not be valued in gold but is broken as easily as glass. Elisha said, “Not so did your teacher Rabbi Akiba say. He said that just as golden and glass vessels may be mended after they are broken, even so may a sinful scholar be made whole again.”
