'Plumbline' in the Bible

The desert owl and the screech owl will possess it,and the great owl and the raven will dwell there.The Lord will stretch out a measuring lineand a plumb line over herfor her destruction and chaos.

He showed me this: The Lord was standing there by a vertical wall with a plumb line in His hand.

The Lord asked me, “What do you see, Amos?”I replied, “A plumb line.”Then the Lord said, “I am setting a plumb line among My people Israel; I will no longer spare them:

For who scorns the day of small things? These seven eyes of the Lord, which scan throughout the whole earth, will rejoice when they see the plumb line in Zerubbabel’s hand.”
