'Light' in the Bible

Then Saul said, “Let us go down after the Philistines by night and take spoil among them until the morning light, and let us not leave a man of them.” And they said, “Do whatever seems good to you.” So the priest said, “Let us draw near to God here.”

Nevertheless, as the Lord God of Israel lives, who has restrained me from harming you, unless you had come quickly to meet me, surely there would not have been left to Nabal until the morning light as much as one male.”

Then Abigail came to Nabal, and behold, he was holding a feast in his house, like the feast of a king. And Nabal’s heart was merry within him, for he was very drunk; so she did not tell him anything at all until the morning light.

Now then arise early in the morning with the servants of your lord who have come with you, and as soon as you have arisen early in the morning and have light, depart.”
