Ver 8. And it came to pass, that while he executed the Priest's office before God in the order of his course, 9. According to the custom of the Priest's office, his lot was to burn incense when he went into the temple of the Lord. 10. And the whole multitude of the people were praying without at the time of incense. ; The Lord appointed by the hand of Moses one High Priest, at whose death another was to succeed in due order. This was observed until the time of David, who by the command of the Lord increased the number of the Priests; and so at this time Zacharias is said to have been performing his Priest's office in the order of his course, as it follows: But it came to pass, when Zacharias was performing the Priest's office in the order of his course before God, according to the custom of the Priesthood, his lot was, &c. AMBROSE; Zacharias seems here to be designated High Priest, because into the second tabernacle went the High Priest alone once every year, not without blood, which he offered for himself and the sins of the people. ; It was not by a new lot that he was chosen when the incense was to be burnt, but by the old lot, whereby according to the order of his Priesthood he succeeded in the course of Abia. It follows, And all the multitude of the people, &c. Incense was ordered to be carried into the Holy of Holies by the High Priest, the whole people waiting without the temple. It was to be on the tenth day of the seventh month, and this day was to be called the day of expiation or propitiation, the mystery of which day the Apostle explaining to the Hebrews, points to Jesus as the true High Priest, who in His own blood has entered the secret places of heaven that he might reconcile the Father to us, and intercede for the sins of those who still wait praying before the doors. AMBROSE; This then is that High Priest who is still sought by lot, for as yet the true High Priest is unknown; for he who is chosen by lot is not obtained by man's judgment. That High Priest therefore was sought for, and another typified, the true High Priest for ever, who not by the blood of victims, but by His own blood, was to reconcile God the Father to mankind. Then indeed there were changes in the Priesthood, now it is unchangeable.
