Yahweh said to me, "Amos, what do you see?" I said, "A plumb line." Then the 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.
Before leaving this passage, it should be noted that some allegations commonly made regarding this passage should be rejected.  "In spite of his plans to punish Israel, for Yahweh they will always remain his beloved and chosen people."[22] As regards the secular, fleshly descendants of Abraham, nothing could be further wrong that such a view, except in its unique application to the true Israel of God, the church of Jesus Christ.  That the rebellious and grossly wicked children of Abraham in the fleshly sense whose notorious rebellions against God and all righteousness are the burden of the entire Old Testament, and who climaxed their unrighteousness by the murder of the Son of God Himself - that that people are, in some sense, still "the chosen people of God" is a monstrous error.
