'Light' in the Bible

And Saul said, Let us go down after the Philistines by night, and plunder them until the morning light, and let us not leave a man of them. And they said, Do whatsoever is good in thy sight. Then said the priest, Let us come near hither to God.

And Saul's servants spoke those words in the ears of David. And David said, Is it a light thing in your eyes to be the king's son-in-law, seeing that I am a poor man, and lightly esteemed?

So and more also do God to the enemies of David, if I leave of all that is his by the morning light any male.

But indeed, as Jehovah the God of Israel liveth, who has restrained me from hurting thee, except thou hadst hasted and come to meet me, there had not been left to Nabal by the morning light any male.

And Abigail came to Nabal; and behold, he held a feast in his house, like the feast of a king; and Nabal's heart was merry within him, for he was drunken to excess; so she told him nothing, less or more, until the morning light.
