'Eye' in the Bible

But why lookest thou on the mote which is in the eye of thy brother, but perceivest not the beam which is in thine own eye?

or how canst thou say to thy brother, Brother, allow me, I will cast out the mote that is in thine eye, thyself not seeing the beam that is in thine eye? Hypocrite, cast out first the beam out of thine eye, and then thou shalt see clear to cast out the mote which is in the eye of thy brother.

The lamp of the body is thine eye: when thine eye is simple, thy whole body also is light; but when it is wicked, thy body also is dark.

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