A.T. Robertson Commentary Matthew 23:35

"that upon you may come all the righteous blood shed on the earth, from the blood of Abel the righteous unto the blood of Zachariah son of Barachiah, whom ye slew between the sanctuary and the altar." — Matthew 23:35 (ASV)

Zachariah son of Barachiah (Ζαχαριου υιου Βαραχιου). Broadus gives well the various alternatives in understanding and explaining the presence of "son of Barachiah" here which is not in Lu 11:51. The usual explanation is that the reference is to Zachariah the son of Jehoiada the priest who was slain in the court of the temple (2 Chronicles 24:20ff.). How the words, "son of Barachiah," got into Matthew we do not know. A half-dozen possibilities can be suggested. In the case of Abel a reckoning for the shedding of his blood was foretold (Genesis 4:10) and the same thing was true of the slaying of Zachariah (2 Chronicles 24:22).
