'Eye' in the Bible

And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?

Or how canst thou say to thy brother, Brother, let me cast out the mote that is in thine eye, when thou thyself beholdest not the beam that is in thine own eye? Thou hypocrite, cast out first the beam out of thine own eye, and then shalt thou see clearly to cast out the mote that is in thy brother's eye.

The lamp of thy body is thine eye: when thine eye is single, thy whole body also is full of light; but when it is evil, thy body also is full of darkness.

For it is easier for a camel to enter in through a needle's eye, than for a rich man to enter into the kingdom of God.
