[37] And he said to the multitudes, When ye see the clouds appear from the west, [38] straightway ye say that there cometh rain; and so it cometh to pass. And when [39] the south wind bloweth, ye say that there will be heat; and it cometh to pass. And when the evening is come, ye say, It will be fair weather, for the heaven has become [40] red. And in the morning ye say, To-day there will be severe weather, for the redness [Arabic, p. 57] of the heaven is paling. Ye hypocrites, ye know to examine the face of the heaven and the earth; but the signs of this time ye know not to discern.
