Luke 1:80

And the child grew, and waxed strong in spirit
That is, John, the son of Zacharias and Elisabeth, grew in stature of body, and increased in wisdom and knowledge, and fortitude in his soul:

and was in the deserts;
or "desert", as the Syriac, Persic, and Ethiopic versions read; not in the wilderness of Judea, where he came preaching, but either of Ziph or Maon, which were near to Hebron; see ( 1 Samuel 23:14 1 Samuel 23:24 1 Samuel 23:25 ) ( Joshua 15:54 Joshua 15:55 ) he was not brought up in the schools of the prophets, nor in the academies of the Jews, or at the feet of any of their Rabbins and doctors; that it might appear he was not taught and sent of men, but of God: nor did he dwell in any of the cities, or larger towns, but in deserts; partly that he might be fitted for that gravity and austerity of life, he was to appear in; and that it might be clear he had no knowledge of, nor correspondence with Jesus, whose forerunner he was, and of whom he was to bear testimony, till such time he did it; and in this solitude he remained,

till the day of his showing unto Israel;
either till the time came that he was to appear before, and be examined by the sanhedrim, that judged of persons fitness and qualifications for the priesthood, in order to be admitted to it; which should have been when he was thirty years of age, but that he was designed for other service; or rather therefore till he appeared in his prophetic office, and showed himself to the people of Israel; to whom he came preaching the doctrine of repentance and remission of sins, administering the ordinance of baptism, giving notice of the near approach of the Messiah, and pointing him out unto the people.
