'Light' in the Bible

Now she had men waiting secretly in the inner room; and she said to him, The Philistines are on you, Samson. And the cords were broken by him as a twist of thread is broken when touched by a flame. So the secret of his strength did not come to light.

Then at the dawn of day the woman came, and, falling down at the door of the man's house where her master was, was stretched there till it was light.
