'Light' in the Bible

Saul said, "Let us go down after [the] Philistines [by] night, and let us plunder them until the morning light, and let us not leave [alive] a man among them." So they said, "Do all that [is] good in your eyes." But the priest said, "Let us draw near to God here."

But {as Yahweh lives}, the God of Israel who has prevented me from harming you, if you had not hurried and come to meet me, surely there would not have been {one male} left alive for Nabal by the light of morning!"

Then Abigail went to Nabal, and look, {he was holding a feast} in his house like the feast of the king. {Nabal was enjoying himself}, and he [was] very drunk, so she did not tell him a thing, {nothing at all}, until the light of morning.

So then, rise early in the morning, [you] and the servants of your lord who came with you. When you rise early in the morning and it is light [enough] for you, leave.
