Red skies

I was reading Matthew 16 the other day and ran upon this verse: (I have to start at the beginning to get the context of it)

The Pharisees also with the Sadducees came, and tempting desired Him that He would show them a sign from Heaven.

He answered and said unto them, "When it is evening, ye say, 'It will be fair weather: for the sky is red.'

And in the morning 'It will be foul weather to day: for the sky is red and lowring.' "

Jesus goes on to call them hypocrrites, that they can discern the skies but not the signs of the times. And that there will be no sign except for the sign of Jonah.

Anyway what stuck out to me was the fact that even in Jesus' time they knew that little saying; 'Red sky in the moring saliors take warning, Red sky at night saliors delight.'

I had always known that saying was old but just the fact that is was over 2,000 years old just stuck out to me.
