Zacharias

1. A person mentioned in Matthew 23:35 Luke 11:51, and most probably designating the son of the high-priest Jehoida, or Barachias, who was stoned to death by order of king Joash for publicly rebuking the king, his court and the people for their growing corruption, 2 Chronicles 24:20-22. Some suppose the prophet Zechariah to be intended; but history gives no account of his death. Others refer it to a Zacharias the son of Baruch, who was put to death just before the destruction of Jerusalem; but it seems unnatural and unnecessary to suppose that Christ here spoke prophetically.

2. A priest belonging to the eighth course or class, called that of Abia, 1 Chronicles 24:1-31, the husband of Elisabeth, and father of John the Baptist. His residence, when not on duty, was in the hillcountry south of Jerusalem. He is known to us by his pious and blameless life; his vision of Gabriel in the temple, promising him a son in his old age; his hesitancy in believing, for which he was visited by a temporary dumbness; his miraculous restoration at the circumcision of his son; and his noble and prophetic song of praise, Luke 1:52; 67-79.

Zacharias

A priest of the course of Abia, the eighth of the twenty-four courses into which the priests had been originally divided by David (1 Chronicles 23:1-19). Only four of these courses or "families" of the priests returned from the Exile (Ezra 2:36-39); but they were then re-distributed under the old designations. The priests served at the temple twice each year, and only for a week each time. Zacharias's time had come for this service. During this period his home would be one of the chambers set apart for the priests on the sides of the temple ground. The offering of incense was one of the most solemn parts of the daily worship of the temple, and lots were drawn each day to determine who should have this great honour, an honour which no priest could enjoy more than once during his lifetime.

While Zacharias ministered at the golden altar of incense in the holy place, it was announced to him by the angel Gabriel that his wife Elisabeth, who was also of a priestly family, now stricken in years, would give birth to a son who was to be called John, and that he would be the forerunner of the long-expected Messiah (Luke 1:12-17). As a punishment for his refusing to believe this message, he was struck dumb and "not able to speak until the day that these things should be performed" (20). Nine months passed away, and Elisabeth's child was born, and when in answer to their inquiry Zacharias wrote on a "writing tablet," "His name is John," his mouth was opened, and he praised God (60-79). The child (John the Baptist), thus "born out of due time," "waxed strong in spirit" (1:80).

The "son of Barachias," mentioned as having been slain between the temple and the altar (Matthew 23:35; Luke 11:51). "Barachias" here may be another name for Jehoiada, as some think. (See ZECHARIAH .)

Zacharias

(Greek form of Zechariah ). Father of John the Baptist. (Luke 1:5) etc. He was a priest of the course of Abia. the eighth of the twenty-four courses who ministered at the temple in turn. He probably lived at Hebron. His wife’s name was Elisabeth. John was born to them in their old age, and the promise of this son was communicated to Zacharias by an angel while he was offering incense and praying in the temple. Son of Barachias, who, our Lord says, was slain by the Jews between the altar and the temple. (Matthew 23:35; Luke 11:61) There has been much dispute who this Zacharias was. Many of the Greek fathers have maintained that the father of John the Baptist is the person to whom our Lord alludes but there can be little or no doubt that the allusion is to Zechariah, the son of Jehoiada, (2 Chronicles 24:20,21) and he may have been called "the son" of Barachias from his grandfather. (B.C. 838.) He is mentioned as being the martyr last recorded in the Hebrew Scriptures (as Abel was the first) -d Chronicles being the last book in their canon.
