I never knew that!

Today, I learned for the first time that the old saying "Red at night Shepherds' delight, red in the morning Sailors's warning." comes from the Bible!
Matthew 16.
"The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven.
 He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’ and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’
