According to Matthew, Jesus accused the Jewish leaders of murdering Zechariah son of Barachiah:

"...Zechariah son of Barachiah whom you murdered between the sanctuary and the altar." (Matthew23:35).

-----------------

Unfortunately, the Zachariah mentioned was slain in Jerusalem, 69 CE; so that Matthew makes Jesus refer to an event that occurred 39 years after his death in the past tense.

Referring to this passage, the Catholic scholar Dr. Hug says: "There cannot be a doubt, if we attend to the name, the fact and its circumstances, and the object of Jesus in citing it, that it was the same Zacharias Barouchos, who, according to Josephus, a short time before the destruction of Jerusalem, was unjustly slain in the temple."

Commenting on this passage, Prof. Newman says: "There is no other man known in history to whom the verse can allude. If so, it shows how late, how ignorant, how rash is the composer of a text passed off on us as sacred truth" (Religion not History, p. 46).

The words, however, do not occur in Luke 11:51, and are possibly interpolated. Zechariah the prophet

Shockingly biblical scholars admit there is an INTERPOLATION !!!!!!!!!!

What a Shame!!!
