Matthew 16:1-4

Young's Literal Translation

16 And the Pharisees and Sadducees having come, tempting, did question him, to shew to them a sign from the heaven,

² and he answering said to them, `Evening having come, ye say, Fair weather, for the heaven is red,

³ and at morning, Foul weather to-day, for the heaven is red -- gloomy; hypocrites, the face of the heavens indeed ye do know to discern, but the signs of the times ye are not able!

⁴ `A generation evil and adulterous doth seek a sign, and a sign shall not be given to it, except the sign of Jonah the prophet;' and having left them he went away.
