'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 a man wipeth a dish, wiping it and turning it upside down.

And I will make justice the line, and righteousness the plummet; and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding-place.

But the pelican and the porcupine shall possess it; and the owl and the raven shall dwell therein: and he will stretch over it the line of confusion, and the plummet of emptiness.

For who hath despised the day of small things? for these seven shall rejoice, and shall see the plummet in the hand of Zerubbabel; these are the eyes of Jehovah, which run to and fro through the whole earth.
