Red skies

From the King James Bible of 1611

Matthew 16:2
He answered, and said vnto them, When it is euening, yee say, It will bee faire weather: for the skie is red.

Matthew 16:3
And in the morning, It will be foule weather to day: for the skie is red and lowring. O ye hypocrites, yee can discerne the face of the skie, but can ye not discerne the signes of the times?

The old saying has an older pedigree than I imagined!
