'Plummet' in the Bible

And I will stretch over Jerusalem the line of Samaria, and the plummet of the house of Ahab, and I will wipe Jerusalem as one wipeth a pan, wiping it and turning it upside down.

And I will appoint judgment for a line, and righteousness for a plummet; and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding-place.

For who hath despised the day of small things? Yea, they shall rejoice even those seven and shall see the plummet in the hand of Zerubbabel: these are the eyes of Jehovah, which run to and fro in the whole earth.
