'Lightened' in the Bible

'The lamp of the body is the eye, when then thine eye may be simple, thy whole body also is lightened; and when it may be evil, thy body also is darkened;

if then thy whole body is lightened, not having any part darkened, the whole shall be lightened, as when the lamp by the brightness may give thee light.'

And we being exceedingly tossed with a tempest, the next day they lightened the ship;

And when they had eaten enough, they lightened the ship, and cast out the wheat into the sea.

And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.
