'Eye' in the Bible

Why do you see the speck in your brother's eye, but fail to see the beam of wood in your own?

How can you say to your brother, 'Brother, let me remove the speck from your eye,' while you yourself don't see the beam in your own? You hypocrite! First remove the beam from your own eye, and then you can see clearly to remove the speck from your brother's eye.

Your eye is the lamp of your body. When your eye is healthy, your whole body is full of light, but when it is diseased, your body is full of darkness.

In fact, it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God."
