Matthew 16:1-4 - The Signs Of The Times
1 The Pharisees and Sadducees came [and attempted] to test Jesus [by] asking Him to perform a [supernatural] sign from heaven.
2 But He answered them, {[{[These words are omitted in most ancient manuscripts: "When the sky is reddish in the evening, you predict fair weather [for the next day]. 3 And when the sky is reddish and overcast in the morning, you predict [that it will be] bad weather that day. You know how to interpret [weather] conditions from the sky, but you cannot interpret the signs of the times [i.e., what will happen in the spiritual realm]"]}]}. 4 "It is an evil and spiritually unfaithful generation of people [that keeps on] looking for a [supernatural] sign; but there will be no [such] sign given to it except the sign of Jonah [i.e., being in the huge fish for three days]." Then He left them and went away.
54 And Jesus also said to the crowds, "When you see a cloud rising in the west, you immediately say, 'A rainstorm is coming up,' and sure enough, it does. 55 And when there is a south wind blowing, you say, 'It is going to be a scorching day,' and sure enough, it is. 56 You hypocrites! You know how to interpret the appearance of the earth and the sky, but why do you not know how to interpret [events of] this present time?
