'Light' in the Bible

And Saul saith, 'Let us go down after the Philistines by night, and we prey upon them till the light of the morning, and leave not a man of them.' And they say, 'All that is good in thine eyes do.' And the priest saith, 'Let us draw near hither unto God.'

And the servants of Saul speak in the ears of David these words, and David saith, 'Is it a light thing in your eyes to be son-in-law to the king -- and I a poor man, and lightly esteemed?'

thus doth God do to the enemies of David, and thus He doth add, if I leave of all that he hath till the light of the morning -- of those sitting on the wall.'

And yet, Jehovah liveth, God of Israel, who hath kept me back from doing evil with thee, for unless thou hadst hasted, and dost come to meet me, surely there had not been left to Nabal till the light of the morning, of those sitting on the wall.'

And Abigail cometh in unto Nabal, and lo, he hath a banquet in his house, like a banquet of the king, and the heart of Nabal is glad within him, and he is drunk unto excess, and she hath not declared to him anything, less or more, till the light of the morning.

and now, rise thou early in the morning, and the servants of thy lord who have come with thee, when ye have risen early in the morning, and have light, then go ye.'
