Luke 3:2

“Annas and Caiaphas being the high priests, etc.] Some difficulty here arises, how these two could be both high priests; when according to the law of God, and the usages of the Jewish nation, there was to be, and was but one high priest at a time: many things are observed by writers, to solve this difficulty: some go this way; that though according to the divine institution, and the practice of former times, there was but one high priest at a time; yet now, through the corruption of the present age, there were two high priests; or at least, which officiated alternately in the same year: but of such a corruption, no instance can be given, even in those corrupt times; and as Maimonides says…”

“Annas and Caiaphas . . . high priests--the former, though deposed, retained much of his influence, and, probably, as sagan or deputy, exercised much of the power of the high priesthood along with Caiaphas (Joh 18:13; Act 4:6). Both Zadok and Abiathar acted as high priests in David's time (Sa2 15:35), and it seems to have become the fixed practice to have two (Kg2 25:18). (Also see on Mat 3:1.) word of God came unto John--Such formulas, of course, are never used when speaking of Jesus, because the divine nature manifested itself in Him not at certain isolated moments of His life. He was the one everlasting manifestation of the Godhead--THE WORD [OLSHAUSEN].”

“Annas and Caiaphas being highpriests - There was, properly speaking, but one high priest of the Jews; yet the name of high priest continued to be given to those who had been in that office, and especially when they still possessed some civil office after they had left the high priesthood. In this case it appears that “Caiapas” was high priest, and Annas “had been,” but had been dismissed from the office. It is highly probable that he still held an office under the Romans, and was perhaps president of the Sanhedrin. He is mentioned before Caiaphas because he was the father-in-law to Caiaphas, and probably was the eldest, and had been longest in office. Instances similar to this may be found…”

“Annas being high priest, and Caiaphas - There could be but one high priest, strictly speaking, at once. Annas was the high priest at that time, and Caiaphas his sagan or deputy. Luke 3:4”

“3:2 Annas and Caiaphas were the high priests: Annas was high priest AD 6–15 and was deposed by the Romans; his son-in-law Caiaphas was the current high priest (AD 18–36). Luke lists both names because Annas still wielded significant power behind the scenes (see John 18:13-14, 24; Acts 4:6). • a message from God came to John: John’s calling as a prophet was similar to that of the Old Testament prophets (see, e.g., Isa 6; Jer 1).”

“Annas: Joh 11:49-51, Joh 18:13, Joh 18:14, Joh 18:24; Act 4:6 the word: Luk 1:59-63; Jer 1:2, Jer 2:1; Eze 1:3; Hos 1:1, Hos 1:2; Jon 1:1; Mic 1:1; Zep 1:1 in: Luk 1:80; Isa 40:3; Mat 3:1, Mat 11:7; Mar 1:3; Joh 1:23 Luke 3:3”
