Thematic Bible: The plumb-line

Thus he showed me: And, behold, LORD stood beside a wall made by a plumb-line, with a plumb-line in his hand. And LORD said to me, Amos, what do thou see? And I said, A plumb-line. Then LORD said, Behold, I will set a plumb-line in the midst of my people Israel. I will not again pass by them any more.
