'Dark' in the Bible

but if thine eye be wicked, thy whole body will be dark. If therefore the light that is in thee be darkness, how great the darkness!

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.

If therefore thy whole body is light, not having any part dark, it shall be all light as when the lamp lights thee with its brightness.

and having gone on board ship, they went over the sea to Capernaum. And it had already become dark, and Jesus had not come to them,

And on the first day of the week Mary of Magdala comes in early morn to the tomb, while it was still dark, and sees the stone taken away from the tomb.
