Matthew 16:1-3

Revised Standard Version Catholic Edition

The Demand for a Sign

16 And the Pharisees and Sad′ducees came, and to test him they asked him to show them a sign from heaven. ² He answered them,^[a] “When it is evening, you say, ‘It will be fair weather; for the sky is red.’ ³ And in the morning, ‘It will be stormy today, for the sky is red and threatening.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.
