'Plummet' in the Bible

And I have stretched out over Jerusalem the line of Samaria, and the plummet of the house of Ahab, and wiped Jerusalem as one wipeth the dish -- he hath wiped, and hath turned it on its face.

And I have put judgment for a line, And righteousness for a plummet, And sweep away doth hail the refuge of lies, And the secret hiding-place do waters overflow.
