'Eyes' 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.

Though they take cover on the top of Carmel, I will go in search of them and get them out; though they keep themselves from my eyes in the bed of the sea, I will give orders to the great snake there and he will give them a bite:

And though they are taken away as prisoners by their attackers, even there will I give orders to the sword to put them to death: my eyes will be fixed on them for evil and not for good.

See, the eyes of the Lord are on the evil kingdom, and I will put an end to it in all the earth; but I will not send complete destruction on Jacob, says the Lord.
