'Sin' in the Bible

And the Lord said to me, Amos, what do you see? And I said, A weighted line. Then the Lord said, See, I will let down a weighted line among my people Israel; never again will my eyes be shut to their sin:

And he said, Amos, what do you see? And I said, A basket of summer fruit. Then the Lord said to me, The end has come to my people Israel; never again will my eyes be shut to their sin.

Those who make their oaths by the sin of Samaria and say, By the life of your God, O Dan; and, By the living way of Beer-sheba; even they will go down, never again to be lifted up.
