  According to the Gospel of Luke, during the reign of king Herod, there was "a certain priest named Zecharias, of the course of Abia", whose wife Elisabeth was also of the priestly family of Aaron. The evangelist states that both the parents were righteous before God, since they were "blameless" in observing the commandments and ordinances of the Lord. When the events related in Luke began, their marriage was still childless, because Elisabeth was barren and they were both very old (Luke 1:5–7).
  The duties at the temple in Jerusalem alternated between each of the family lines that had descended from those appointed by king David (1st Chronicles 24:1–19). [1] Luke states that during the week when it was the duty of Zechariah's family line to serve at "the temple of the Lord", the lot for performing the incense offering had fallen to Zechariah (Luke 1:8–11). The Gospel of Luke states that while Zechariah ministered at the altar of incense, an angel of the Lord appeared and announced to him that his wife would give birth to a son, whom he 

But David, being desirous of ordaining his son king of all the people, called together their rulers to Jerusalem, with the priests and the Levites; and having first numbered the Levites, he found them to be thirty-eight thousand, from thirty years old to fifty; out of which he appointed twenty-three thousand to take care of the building of the temple, and out of the same, six thousand to be judges of the people and scribes, four thousand for porters to the house of God, and as many for singers, to sing to the instruments which David had prepared, as we have said already. He divided them also into courses: and when he had separated the priests from them, he found of these priests twenty-four courses, sixteen of the house of Eleazar, and eight of that of Ithamar; and he ordained that one course should minister to God eight days, from sabbath to sabbath. And thus were the courses distributed by lot, in the presence of David, and Zadok and Abiathar the high priests, and of all the rulers; and that course which came up first was written down as the first, and accordingly the second, and so on to the twenty-fourth; and this partition hath remained to this day. He also made twenty-four parts of the tribe of Levi; and when they cast lots, they came up in the same manner for their courses of eight days. He also honored the posterity of Moses, and made them the keepers of the treasures of God, and of the donations which the kings dedicated. He also ordained that all the tribe of Levi, as well as the priests, should serve God night and day, as Moses had enjoined them. 

For what I have now said is publicly known, and supported by the testimony of the whole people, and their operations are very manifest; for although there be four courses of the priests, and every one of them have above five thousand men in them, yet do they officiate on certain days only; and when those days are over, other priests succeed in the performance of their sacrifices, and assemble together at mid-day, and receive the keys of the temple, and the vessels by tale, without any thing relating to food or drink being carried into the temple; nay, we are not allowed to offer such things at the altar, excepting what is prepared for the sacrifices.

Zacharias (1.) 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 Chr. 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).

Now as for the affairs of the Jews, they grew worse and worse continually, for the country was again filled with robbers and impostors, who deluded the multitude. Yet did Felix catch and put to death many of those impostors every day, together with the robbers. He also caught Eleazar, the son of Dineas, who had gotten together a company of robbers; and this he did by treachery; for he gave him assurance that he should suffer no harm, and thereby persuaded him to come to him; but when he came, he bound him, and sent him to Rome. Felix also bore an ill-will to Jonathan, the high priest, because he frequently gave him admonitions about governing the Jewish affairs better than he did, lest he should himself have complaints made of him by the multitude, since he it was who had desired Caesar to send him as procurator of Judea. So Felix contrived a method whereby he might get rid of him, now he was become so continually troublesome to him; for such continual admonitions are grievous to those who are disposed to act unjustly. Wherefore Felix persuaded one of Jonathan's most faithful friends, a citizen of Jerusalem, whose name was Doras, to bring the robbers upon Jonathan, in order to kill him; and this he did by promising to give him a great deal of money for so doing. Doras complied with the proposal, and contrived matters so, that the robbers might murder him after the following manner: Certain of those robbers went up to the city, as if they were going to worship God, while they had daggers under their garments, and by thus mingling themselves among the multitude they slew Jonathan [19] and as this murder was never avenged, the robbers went up with the greatest security at the festivals after this time; and having weapons concealed in like manner as before, and mingling themselves among the multitude, they slew certain of their own enemies, and were subservient to other men for money; and slew others, not only in remote parts of the city, but in the temple itself also; for they had the boldness to murder men there, without thinking of the impiety of which they were guilty. And this seems to me to have been the reason why God, out of his hatred of these men's wickedness, rejected our city; and as for the temple, he no longer esteemed it sufficiently pure for him to inhabit therein, but brought the Romans upon us, and threw a fire upon the city to purge it; and brought upon us, our wives, and children, slavery, as desirous to make us wiser by our calamities.
