so that the blood of all the prophets that has been shed from the foundation of the world may be required of this generation,

from the blood of Abel to the blood of Zechariah, who perished between the altar and the temple building. Yes, I tell you, it will be required of this generation!

And the master praised the dishonest manager, because he had acted shrewdly. For the sons of this age are shrewder than the sons of light with regard to their own generation.

But first it is necessary [for] him to suffer many [things], and to be rejected by this generation.

Truly I say to you that this generation will never pass away until all [things] take place!
