'Light' in the Bible

You led them by day with a column of cloud and with a column of fire by night, to give them light on the way that they were to go.

But you in your many mercies did not abandon them in the desert. The column of cloud [that was] over them in the day did not cease to leave them on the way, and the column of fire by night [that] gave light to them on the way that they went.
