2 Peter 1:19
We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
"I should have known, but it just never dawned on me."
Harriet Beecher Stowe, Uncle Tom's Cabin (1852)
