The voice of thy thunder was in the heaven: the lightnings lightened the world: the earth trembled and shook.

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.
