 He was killed in the priests' courtyard of the Temple on a Sabbath which was likewise the Day of Atonement.Later, when Nebuzar-adan, the captain of Nebuchadnezzar's body-guard, came to destroy the Temple, he saw Zechariah's blood which had been boiling since his murder.The Assyrian asked the Jews what that phenomenon meant, but when they replied that it was the blood of sacrifices, he proved the falsity of their answer.
