'Plumb Line' in the Bible

I will stretch out over Jerusalem the measuring line of Samaria and the plumb line of the house of Ahab, and I will wipe Jerusalem as one wipes the dish; he wipes it and turns it on its face.

And I will make justice [the] measuring line, and righteousness [the] plumb line; and hail will sweep away [the] refuge of lies, and waters will flood over [the] hiding place.

But [the] large bird and [the] hedgehog shall take possession of it, and [the] owl and [the] raven shall live in it. And he shall stretch [the] measuring line of confusion out over it, and [the] plumb line of emptiness.

Thus He showed me [a vision], and behold, the Lord was standing by a vertical wall with a plumb line in His hand [to determine if the wall was straight or if it needed to be destroyed].

The Lord said to me, “Amos, what do you see?” And I said, “A plumb line.” Then the Lord said,“Behold, I am setting a plumb line [as a standard]Among My people Israel [showing the defectiveness of the nation, requiring judgment].I shall not spare them any longer. [The door of mercy is shut.]

For whoever has despised the day of small [things] will rejoice and will see the {plumb line} in the hand of Zerubbabel." These seven [are] the eyes of Yahweh which [are] ranging {throughout the whole earth}.
