'Plummet' in the Bible

I will stretch over Jerusalem the measuring line of Samaria and the plummet of the house of Ahab; and I will wipe Jerusalem clean just as one wipes a [dirty] bowl clean, wiping it and turning it upside down.

“I will make justice the measuring lineAnd righteousness the mason’s level;Then hail will sweep away the refuge of liesAnd waters will flood over the secret [hiding] place.

But the pelican and the porcupine will take possession of it;The owl and the raven will dwell in it.And He will stretch over it (Edom) the measuring line of desolationAnd the plumb line of emptiness.

Who [with reason] despises the day of small things (beginnings)? For these seven [eyes] shall rejoice when they see the plumb line in the hand of Zerubbabel. They are the eyes of the Lord which roam throughout the earth.”
