'Light' in the Bible

But it was not the Lord's purpose to send destruction on the family of David, because of the agreement he had made with David, when he said he would give to him and to his sons a light for ever.

Go and get directions from the Lord for me and for those who are still in Israel and for Judah, about the words of this book which has come to light; for great is the wrath of the Lord which has been let loose on us, because our fathers have not kept the word of the Lord or done what is recorded in this book.

And the king went up to the house of the Lord, with all the men of Judah and the people of Jerusalem, and the priests and the Levites and all the people, small and great; and they were present at his reading of the book of the law which had come to light in the house of the Lord.
