'Plumbline' in the Bible

I'll stretch out over Jerusalem the measuring line that is Samaria and the plumb line that is Ahab's dynasty. Then I'll wipe Jerusalem like one wipes a dish, wiping it and turning it upside down!

And I will make justice the measuring line, and righteousness the plumb line; hail will sweep away your refuge of lies, and floods will overflow your hiding place.

This is what he showed me: Look! The Lord was standing upon a wall that stood straight and true, with a plumb line in his hand.

And the LORD was asking me, "What do you see, Amos?" I replied, "A plumb line." So the Lord said, "Look, I have set a plumb line in the midst of my people Israel. I will no longer spare them.

For who has despised the time of insignificant things? They will rejoice to see the plumb line in the hand of Zerubbabel. These seven lights represent the eyes of the LORD, which are looking throughout all of the earth."
