Red sky at morning

"The common phrase "red sky at morning" is a line from an ancient rhyme often repeated by mariners:

Red sky at night, shepherds´ delight.Red sky at morning, shepherds take warning

The concept is over two thousand years old and is referenced in the New Testament as established wisdom that prevailed among the Jews of the Second Temple Period by Jesus in Matthew 16:2-3." - (en.wikipedia.org 30.03.2020)
