The Almighty appointed to Moses that there should be but one high priest at a time, to whom, at his decease, a successor should be chosen. This rule obtained till the time of David, by whom, by the inspiration of God, many were appointed at once. (1 Paralipomenon chap. xxiv.) According to this regulation, Zachary (Zacharias) is said to perform the office of priest, according to the order of his course. (Ven. Bede)

Zacharias seems here to be described as high priest, who once a year entered alone in the inward sanctuary with the blood of the victims, which he offered for himself and the sins of the people. (St. Ambrose)

He was not chosen by a fresh lot to offer up incense, but by a previous lot, according to which the family of Abia succeeded to the office of high priest. The people waited without, according to Leviticus xvi. 12.; whilst the high priest carried the incense into the holy of holies, on the 10th day of the 7th month. (Ven. Bede)

Of the course of Abia.[2] What we read in the Greek for course, is commonly put for the employment of one day, but here for the functions of a whole week. For by appointment of David, (1 Paralipomenon xxiv,) the descendants from Aaron were divided into 24 families; of which the eighth was Abia, from whom descended this Zacharias, who at this time was in the week of his priestly functions. (Witham)

It is worthy of remark, that there were three Herods. The first was the one here spoken of, (surnamed Ascalonite, from his palace in the city of Ascalon, in Palestine) the same who murdered the Innocents. The second was the son of the first, (surnamed Antipas) who derided Christ at the time of his passion, the same who beheaded the Baptist. The third was Herod Agrippa, who beheaded St. James, imprisoned St. Peter, and who was afterwards, for his great pride, stricken by an angel, and devoured by worms. Our Saviour was born in the reign of the first Herod, by whom the prophecy of Jacob, related in the book of Genesis (chap. xlix,) was fulfilled: The sceptre shall not be taken, &c. Herod was an IdumÃ¦an, and made king of the Jews by the Romans. The Jews, after they entered the land of promise, were first governed by judges, until Saul: then by kings, until the Babylonian captivity; after that by high priests, until the time of Hyrcanus, whom Herod having killed, succeeded. From that period to the present day, they have been governed by strangers. (Ven. Bede, and Denis the Carthusian)

Elizabeth was of the race of Aaron, by her father; but her mother was probably of the race of David, from whom the blessed Virgin, cousin of Elizabeth, descended. See below, ver. 36.
