“When you see
The south wind blowing,
You say.
‘There will be
Scorching heat.’
Thus,
It happens.”
καὶ ὅταν νότον πνέοντα, λέγετε ὅτι Καύσων ἔσται, καὶ γίνεται
Luke uniquely indicated that Jesus said that when they saw the south wind blowing (καὶ ὅταν νότον πνέοντα), they would say that there would be scorching heat (λέγετε ὅτι Καύσων ἔσται). Thus, it happened (καὶ γίνεται). Jesus continued with his weather commentary. The winds from the south were coming off the southern desert bringing more heat. Do you like hot weather?
