39 And sending away the crowds, Jesus got into the boat and came to the region of Magadan.

Matthew 16

16:1

The Pharisees and Sadducees came up, and testing Jesus, they asked Him to show them a sign from heaven.

2 But He replied to them, "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 appearance of the sky, but cannot discern the signs of the times?

4 "An evil and adulterous generation seeks after a sign; and a sign will not be given it, except the sign of Jonah." And He left them and went away.

NASU

9 About four thousand were there; and He sent them away.

10 And immediately He entered the boat with His disciples and came to the district of Dalmanutha.

11 The Pharisees came out and began to argue with Him, seeking from Him a sign from heaven, to test Him. 

12 Sighing deeply in His spirit, He said, "Why does this generation seek for a sign? Truly I say to you, no sign will be given to this generation."

13 Leaving them, He again embarked and went away to the other side.

NASU

Luke 12:54-56
54 And He was also saying to the crowds, "When you see a cloud rising in the west, immediately you say, "A shower is coming,' and so it turns out.

55 "And when you see a south wind blowing, you say, "It will be a hot day,' and it turns out that way.

56 "You hypocrites! You know how to analyze the appearance of the earth and the sky, but why do you not analyze this present time?
