'Light' in the Bible

and he readeth in it before the broad place that is before the water-gate, from the light till the middle of the day, over-against the men, and the women, and those intelligent, and the ears of all the people are unto the book of the law.

and Thou, in Thine abundant mercies, hast not forsaken them in the wilderness -- the pillar of the cloud hath not turned aside from off them by day, to lead them in the way, and the pillar of the fire by night, to give light to them and the way in which they go.
