'Enlightened' in the Bible

But Jonathan heard not when his father charged the people with the oath: wherefore he put forth the end of the rod that was in his hand, and dipped it in an honeycomb, and put his hand to his mouth; and his eyes were enlightened.

Then said Jonathan, My father hath troubled the land: see, I pray you, how mine eyes have been enlightened, because I tasted a little of this honey.
