The Pharisees and Sadducees came up, and testing Jesus, they asked Him to show them a [a]sign from heaven. 2 But He replied to them, “[b]When it is evening, you say, ‘It will be fair weather, for the sky is red.’ 3 And in the morning, ‘There will be a storm today, for the sky is red and threatening.’ Do you know how to discern the [c]appearance of the sky, but cannot discern the signs of the times? 4 An evil and adulterous generation seeks after a [d]sign; and a [e]sign will not be given it, except the sign of Jonah.” And He left them and went away.
