Matthew 16:2 — 3, “But He replied, “When evening comes, you say, ‘The weather will be fair, for the sky is red,’ and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but not the signs of the times.” Red sky at night, sailors delight, red sky in morning, sailors take warning. Yes this familiar saying does come directly from the Bible.
