Zephaniah 1:1

Here is, I. The title-page of this book (Zep 1:1), in which we observe, 1. What authority it has, and who gave it that authority; it is from heaven, and not of men: It is the word of the Lord. 2. Who was the instrument of conveying it to the church. His name was Zephaniah, which signifies the servant of the Lord, for God revealed his secrets to his servants the prophets. The pedigree of other prophets, whose extraction we have an account of, goes no further back than their father, except Zecharias, whose grandfather also is named. But this of Zephaniah goes back four generations, and the highest mentioned is Hizkiah; it is the very same name in the original with that of Hezekiah king of Judah (Kg2 18:1), and refers probably to him; if so, our prophet, being lineally descended from that pious prince, and being of the royal family, could with the better grace reprove the folly of the king's children as he does, Zep 1:8. 3. When this prophet prophesied - in the days of Josiah king of Judah, who reigned well, and in the twelfth year of his reign began vigorously, and carried on a work of reformation, in which he destroyed idols and idolatry. Now it does not appear whether Zephaniah prophesied in the beginning of his reign; if so, we may suppose his prophesying had a great and good influence on that reformation.
