That the blood of all the prophets, which was shed from the foundation of the world, may be required of this generation;
Read Chapter 11
Irenaeus of Lyons
AD 202
"In like manner, too, did the Lord say to those who should afterwards shed His blood, "All righteous blood shall be required which is shed upon the earth, from the blood of righteous Abel to the blood of Zacharias the son of Barachias, whom ye slew between the temple and the altar. Verily I say unto you, All these things shall come upon this generation."
