Matthew 16:1-3

1 The Pharisees and Sadducees came to Jesus, wanting to trick him. So they asked him to show them a miracle from God.

2 Jesus answered, "At sunset you say we will have good weather, because the sky is red.

3 And in the morning you say that it will be a rainy day, because the sky is dark and red. You see these signs in the sky and know what they mean. In the same way, you see the things that I am doing now, but you don't know their meaning.
