Luke 12:55
And when the south wind blows, you say, ‘It will be hot,’ and it is.
What it says
They can also sense a south wind and know heat will follow.
What it is doing
The verse adds another ordinary sign they correctly read.
In context
54Then Jesus said to the crowds, “As soon as you see a cloud rising in the west, you say, ‘A shower is coming,’ and that is what happens. 55And when the south wind blows, you say, ‘It will be hot,’ and it is. 56You hypocrites! You know how to interpret the appearance of the earth and sky. Why don’t you know how to interpret the present time?
